In Timelock, the thrilling finale to the Caretaker Trilogy, the end of life as we know it has arrived, and history will be made -- or lost -- at the hands of one young hero.

Jack Danielson has spent the last year saving the oceans and the Amazon, attempting to fulfill a prophecy that was written before his birth. Now he's more than ready to get back to life as a typical teenager and spend some quality time with his girlfriend, P.J. Too bad the world has other plans.

Wrenched away once more from those he knows and loves, Jack is thrust through time to the fiery deserts of the future and the frozen tundra of the Arctic, battling cyborgs, zombie warlocks, and scorpions the size of tanks. At least he has Gisco -- everyone's favorite surly telepathic canine -- to keep him company, not to mention the Ninja Babe, Eko. And he will finally be reunited with the parents who abandoned him so long ago, in order that he might save their dying planet.

But it isn't only a race to save Earth. As the clock ticks down before the final confrontation with the dreaded Dark Lord, Jack must decide once and for all who he really is -- prince of the future or humble human of the present -- and choose between the two women who love him.

David Klass

35 books169 followers
David Klass is the author of many young adult novels, including You Don’t Know Me, Dark Angel, and Firestorm (The Caretaker Trilogy). He is also a Hollywood screenwriter, having written more than twenty-five action screenplays, including Kiss the Girls, starring Morgan Freeman and Ashley Judd, Walking Tall, starring The Rock, and Desperate Measures, starring Michael Keaton and Andy Garcia. Klass grew up in a family that loved literature and theater—his parents were both college professors and writers—but he was a reluctant reader, preferring sports to books. But he started loving the adventure stories his parents would bring home from the library—particularly Jack London, Robert Louis Stevenson and Alexandre Dumas. After his sister twice won a story contest in Seventeen magazine, Klass decided he would win it too, and when he was a senior in high school, he did, publishing his first story, “Ringtoss,” in the magazine. He studied at Yale University, where he won the Veech Award for Best Imaginative Writing. He taught English in Japan, and wrote his first novel, The Atami Dragons, about that experience. He now lives in New York with his wife and two children.

When I fought 2 other nerds in my school media center to get to the long lusted for final book of david klass's Caretaker trilogy, I was hoping to get thebest book i ever read. Well... at least i thought i was but i soon found out that i thought wrong. I soon found out that only in an ideal world where there's no global-warming and where the-great-dog-god comes down to fart his blessings down on us, that the final book would be awesome. It's not. The book isn't terrible it's just somewhat disappointing like a straight A student only getting B's and C's on his report card. If you like the other books read it just to find out how the series ends.

I liked the gorm!

Ending was disappointing, particularly in the resolution of the love triangle. (Actually, is it a triangle when two people like the same person, who likes both? Maybe a triangle requires more complicated and unrequited liking....)

Interesting to see the future wasteland and meet Jack/Jair's family, I suppose.

I still just don't really connect that well with (or like?) the main character, which is a real shame.

I don't know...I also still think the environmental message is too heavy-handed (and too absolute) to be that effective with most readers, but maybe that's just me.

Im Finale der Trilogie wird Jack gezwungen in die Zukunft zu reisen, um seinen Vater zu retten. Nur mit seiner Hilfe kann die Arktis und somit unsere Erde noch gerettet werden. Wird es Ihnen gelingen ihren Feind zu besiegen und damit das Überleben der Erde zu sichern?

Ich muss sagen, dass ich definitiv schon bessere Bücher, aber auch schlechtere gelesen habe. Nur phasenweise konnte mich die Geschichte überzeugen und fesseln. Die Darstellung der Zukunft konnte mich nicht überzeugen und am Ende fehlte mir etwas, damit die Geschichte wirklich rund abgeschlossen wäre.

“Timelock” is heavily sci-fi and entertaining. You should probably read the other two books first before you read this final book. Jumping straight into this book I was confused. This book is made to be a conclusion. Starting in “Timelock” you won’t have an introduction or a lot of information about the characters. I was certainly hoping for a bit more information about Jack. I was never truly drawn into the book.
Jack Danielson is the main character and is taken to the future leaving behind the ones he loves. He saves both his parents from the Dark Army. Jack sees his parents future planet which is a scorching desert. He quickly realizes that the creatures of the planet don’t have easy lives. The food is unsavory but they eat it to survive.
Reading “Timelock” means you should be quite invested in action and sci-fi. I wouldn’t recommend this book if you’ll looking for a calm and relaxing story where you fall in love with the characters. Personally I was never interested in Jack or any of the other characters. It's definitely not one of the best books you could ever read but still entertaining.
This book mostly tries to get you to see the environmental side. If you don’t take care of your planet then you could ruin it. You might start questions your definition of home with the story. “Timelock” is just crammed full of action to make up for its lackluster ending. The ending is nothing spectacular and you could probably guess what happens.

Of all the books in this series, this was my least favorite. The main thing that kept me reading was the constant action and fighting. The plot line was kind of weird and nothing really important happened until the end. There was also one part when the characters explained how narwhals' horns are actually magic wands, that made no sense. If you've read the previous two books you should probably read this one too, but it's not needed.

It was a good book. It made me want to read more because the action in it was good and continous.

Jack Danielson is just a boy who is more than ready to get back to a normal life and spend some quality time with his girlfriend. He has spent the last year risking everything to save the oceans and the Amazon. Too bad the world has other plans. Wrenched away once more from the woman he loves, Jack is thrust through time to the fiery deserts of the future to battle cyborgs, zombie warlocks, and scorpions the size of tanks. But he doesn’t just have to save the Earth. As the final confrontation with the dreaded Dark Lord looms, Jack must decide once and for all who he really is. Prince of the future or humble human of the present and choose between the two women who love him. An impossible decision, if he stays alive long enough to. What i like about this book is that its a science-fiction book, and therefore is not bound to exploring the normal plains of existence, it goes far and beyond in the unimaginable and unfathomable.

In this third installment of the Caretaker Trilogy, David Klass has Jack whisked away to the future to fulfill his destiny. The picture he paints of a bleak and barren earth devoid of beauty and teeming life is a heart-rending nightmare and if you weren't already a fanatic of preserving the earth for mankind and all it's creatures, you might just change your mind. I was very please at how everything was resolved at the end. Even though you suspect a particular outcome, it is always nice to have a few surprises accompany it. Great writing. Fantastic message. Excellent speed. Loved the sentence fragments!

That's a no for me. I'm talking about the ending. It is a huge no-no. I didn't like it. I didn't want to read it. My body is repulsed by it. I hated it.

But the story is great, as for the other books. I didn't want to be played like that by the author. the ending made me want to cry. But that's okay. It was an epic series, one of the best i have ever read.

I wish that the French editor would have published the third book in French because the cover was everything, but they didn't so I had to buy it in English. And it looks kinda ugly in my bookshelf.

This is the second book in a trilogy. While I didn't enjoy it as much as the first one, it was still a good story. I liked seeing the main character Jack deal with the truth about his heritage as he faces another nemesis who is determined to destroy the Amazon rain forest. There wasn't as much character development in this story as the first one, but it was enough to keep me reading to the end. I will read the last book, just to see how it all ends.

Jack Danielson has been sent back to the future to help his father escape from the dark lord and safe the earth. The story from the second story leads into this story well. This is the third book in the series and it is great. Jack must go back through time to retrieve the star of Dann, and to defeat the Omega box and the dark lord. Jack finally meets his mother and father, and must go onto a daring rescue mission to get his father. This story was written well and I enjoyed it very much.

Okay so I read this book thinking it would be the boring book of the series of three. So getting into the book I wasn't to interested. Then I got to reading it and I got hooked. I'm Not that big of a reader like I don't like to read but this book changed my mind. Its a adventure filled book with twist and turns I did not see coming. I suggest this book to people who like adventure and twists in the story that correspond with past and future books in a series.

The finale of the series is about saving the polar ice caps and traveling back to Jack's time period. We do finally get to see the future. That alone is worth the read. This one is more interesting than the second book in the series. A worthy finale for the series. Lots of action and finally some answers.

dans la lignée des deux précédents, futuriste et dystopique, de l'action un chine qui communique par télépathie, des allers-retour futur/ passé , des personnages attachants;tout pour faire une belle trilogie. David Klass l'a bien compris. Voilà la fin de la trilogie du guardien, pourtant peu connue mais qui mériterais d'y jeter un coup d'oeil plus sérieux :)

Jack meets his real mother and father and has a final showdown with the Dark Master. This was a great series about the harm we are not doing to the planet and although this is fantasy, there could really be a Dark Master in the future of the Earth if we don't take steps now to correct the harm we are doing.
I liked this whole series - but you have to be into fantasy.

This is the final book in a trilogy. It is a good SF book for young adults and has a strong environmental message. The series would be an excellent one to use in a classroom setting to bring up relevant issues such as global climate change and extinction of species.

Last of a trilogy. Fast paced books about a boy sent from the future to grow up in our time so he can save the world from environmental disaster. Fast-paced, humorous and very entertaining. Strong environmental message which is sometimes a little too much. Not great literature but a fun read.

Weakest of the series. Everything felt like a shadow of itself - the villains, the "tension" between Jack's present & future lives, Pj & Eko. Awful epilogue, too. But, the first two are still worth it!

A very good conclusion to an excellent series. For all of you happy-ever-after lovers, you will like this one. You won't love it, mostly because people die and people get left behind, but you will like and enjoy it. I loved this series, I loved the characters, and I loved the plot. Read it!

This was SUCH a slow read but I'm glad I finally managed to finish it. Even though it was corny I liked the way the series ended and Earth was saved. It's nice to think that maybe there's a Jack Danielson in all of us.

It was good. Jack goes into the future to rescue his dad from the Dark Army. After he his free him and Jack goes back into the past to stop the Dark Lord and the Omega Box from melting the polar ice caps. To stop things from happening in the past Kidah sacrifices himself to freeze the time stream.

Basically enjoyed the series except for when the SF took over. What I found annoying was the countless times our protagonist, Jack, found himself in doomed scenarios. Got a little old after a while.
