Which of these sounds the best as a book?

I am in the middle of writing a heap of books and I want to know which one you would read:

>Taking back the Earth- Dinosaurs are taking the Earth back again.A group of seven teens and two adults have to help stop the dinosaurs from destroying the Earth with a little help along the way. The book is set in the town of Geelong, Australia.

>Luke and Jester- A teenaged girl gets kicked out of her high school and forced to move schools to Dyson High. She meets a boy named Luke and his mischievous gang and they both help each other to get through life's hard times.

>Adaption- The world has changed over the last few years. But in this book, it's 2050. Animals are nothing like they used to be, they are bigger, stronger and twice as ferocious. Grace joins a team of people to try and keep the animals under control.

>Nicole Night- A place named 'Falkor' has demanded war against Earth, but two of these Folkorians have decided to rebel. Nicole, who is part tiger and Greyson, who is part wolf, start another army to go against the king of Chaos and his goons.

>Bob and John- Two step brothers named John and Bob are forced to learn to get along once a villain known as Insanity kidnaps their wives. They soon find out that it takes one to know one, they hire a supervillain to help them find Insanity, but after the villain refuses do work alongside them, they have to go to extreme measures and drug him, making it almost like working with a three year old child.

I know these are really bad summaries and probably all stupid stories but if you honestly had to pick one, which one would you pick?
