Since ancient times, the great demon prison Zzyzx has protected the world from the most dangerous servants of darkness, including Gorgrog, the Demon King. After centuries of plotting, the Sphinx is on the verge of recovering the five artifacts necessary to open the legendary prison. Facing the potential of a world-ending calamity, all friends of light must unite in a final effort to thwart the Sphinx s designs and find a safe home for the five artifacts. To this end, Kendra, Seth, and the Knights of the Dawn will venture far beyond the walls of Fablehaven to strange and exotic magical preserves across the globe, where the end of every quest becomes the beginning of another. In this explosive series finale, allegiances will be confirmed and secrets revealed as the forces of light and darkness collide in a desperate struggle to control the keys to the demon prison.

Book arrived damaged as the front cover is bent in 2 places. Not a big deal, but I had wanted it to look in new condition since it was a gift for my child. We love the story and have it on audiobook already.

5.0 out of 5 stars Fablehaven: A Great Book Series For The Whole Family!
Reviewed in the United States on April 21, 2010
Verified Purchase
We discovered these books when we got the first book for our third son, who was then turning thirteen. Two years later, Mom, Dad and sons ages 13, 15 and 18 are all hooked. These books provide really good fantasy entertainment and excellent writing.
I wouldn't recommend them for kids under 11 or so, depending on what they are accustomed to reading, because the books can be pretty frightening, and they deal with very serious subjects, such as death, loss, and betrayal. The stories are very well woven, and there are plenty of plot twists to keep you guessing. The characters definitely come to life, and more then once, I wanted to send Seth to his room for a week or two. Read the books, and you'll know just what I mean. I'm sorry to see the series come to an end, but looking forward to seeing what's next.
Brandon Mull is a nice person as well as being one of my favorite authors now; three of my sons and I drove over 200 miles in 2009 to have a few of the books signed, and he was very nice, and still keeps in contact with my son Nick, who is his biggest fan.

5.0 out of 5 stars Well done. A favorite for my 11 year old, 8 year old and me.

We have enjoyed all the books of this series. Some parts of the Fablehaven books, and this book in particular, are blatantly moralistic. A little too blatant for an adult book, but very appropriate for a children's book. I really liked that for the most part because it is a springboard for meaningful conversations with my kids.

As for book 5. It is fast paced and engaging. For the past three days my 11 year old daughter has read it every recess and then every spare minute we've had we have sat side by side both reading from our places in the book. I am reading it to my 8 year old son, but it will be another week before the two of us finish. It is a relief to have a book that I not only have NO hesitation recommending for my kids, but one that I WANT them to read because of the good lessons in it AND for its great entertainment value.

I think Brandon Mull did a great job leading up to an unexpected conclusion of events for the most part. Aside from two little "tidy" parts near the end (which I don't list for "spoiler reasons") I think everything was done very very well. I even like the loose ends as they lead to great imaginative adventures if you want to continue the story on your own.

Bravo!

We have enjoyed all of Brandon Mull's books (Pingo included) and look forward to more!

5.0 out of 5 stars Great Story, Great Ending, No Spoilers

It is not often I give a book a 5/5 stars but this book deserves it. I'm sure most of you have already read the other four fablehaven stories so you all have unanswered questions about the characters and story developement. The 5th book, Keys to the Demon Prison, answers all of your questions and more. It ends rather well and doesn't leave you hanging or wishing for more. It is one of those rare books that is so well written you can concede to the fact the series is over and you are happy.

The plot varies a bit from the other books as Kendra and Seth go on completely seperate adventures for the entire story (until the very last 50 pages or so). Seth grows a bit more mature, Kendra move Fierce, and the satyrs get to drive a truck and be more involved!

I cannot say much more then this in the review because I don't want to spoil anything for anyone. Some of these reviews should be avoided until you have read it all!!! Anyway, this book is great. I'd imagine this is my favorite book followed closely by book number three, the shadow plague. This book is in Hardcover, has beautiful cover art, and is thicker than the others so you have a bit more reading to do. Happy Fable Reading :)

I read Fablehaven aloud to my kids (6-14) and they love it. They clamor for me to read every night and hurry to get ready for bed in the hopes if getting more chapters. The characters continue to be terrific, and Mull doesn't disappoint with surprising twists. Keys to the Demon Prison is particularly action-packed and it's one exciting ride. I definitely recommend this series to anyone young or young at heart. I read them all myself before I read them to my kids because I just can't stop after my kids go to sleep, so I get ahead and finish within a few days. Also check out the Dragonwatch series, which is a sequel to the Fablehaven series!

The entire Fablehaven series is outstanding. It immerses you in a fantastic world without having to resort to cheap gimmicks like sex and graphic violence. Safe and entertaining to read for all ages. I read them to my kids when they were 5 or 6 (now 17+). This last time, I just read them for my own enjoyment. Highly recommended!!

I read this series aloud to my 9 and 11 year old daughters and we loved it! The author uses rich vocabulary and develops great characters. The stories were captivating enough to keep us all reading way too late many nights. I appreciated the opportunity to discuss new vocabulary and the introduction of many mythical creatures that will surface again in literature the girls will likely read for school down the road. It's a great series to read along with your kids.

Llegó tal como lo esperaba, en perfectas condiciones y muy rápido. Más allá del proceso de venta y entrega, es el quinto y último libro de la saga, por lo que recomendaría leer los primeros cuatro antes. Fantasía/Ciencia Ficción y, en mi opinión, buenas historias.

Reviewed in Germany on April 6, 2010

Mit "Keys to the Demon Prison" beendet Brandon Mull seine Fablehaven Serie. Handlungsbögen, die geschickt über die vergangenen vier Romane aufgebaut wurden, werden gekonnt zu Ende geführt.
Kurz zum Inhalt: Die Sphinx versucht nach wie vor die Schlüssel zum Dämonengefängnis von Zyzyx zu vereinen. Mit alten Verbündeten und neuen Freunden stellen sich Kendra, Seth und ihre Großeltern der Gefahr entgegen. Geheimnisse werden enthüllt, Opfer gebracht und auch die Feenkönigin setzt ihre Macht ein um die Helden zu unterstützen. Als Seth jedoch einen folgenschweren Fehler begeht, müssen die Karten neue gemischt werden.
Gewohnt spannend entführt Brandon Mull in sein reiches Fablehaven-Universum. Mit großer Lust am fabulieren mischt er wieder bekannte Geschöpfe aus Mythologie und Märchen mit einer spannenden Abenteuerhandlung, die nicht nur Jugendliche begeistern wird. Wer also wissen will, was es mit Zyzyx auf sich hat, welche Rolle den "Eternals" dabei zufällt und wie die Fablehaven-Saga endet, dem sei "Keys to the Demon Prison" uneingeschränkt ans Herz gelegt.
