Supersaurs 1: Raptors of Paradise | 
pickWOW!
Without going into spoilers, this book is filled with action, adventure, and a bit of humor. I have to give the author and illustrator big props for accurately portraying the raptors and rexes with feathers. I also like how the dinosaurs were portrayed as actual animals, and not as monsters, unlike some popular dinosaur media. I am greatly looking forward to reading the rest of the series.
