Gordon Korman, who wrote Schooled among other things, has written a book called Zoobreak, about kids who decide to rescue zoo animals, breaking them out of one (bad) zoo and into another (better) one. Sounds like a nearly impossible task.
If you’ve been reading the Book of Time books by Guillaume Prevost you will be pleased to hear that you can now read the next story in the series, The Circle of Gold. Sam must go back in time to see his mother, but he’s not good at getting the time right, which sees him travelling to Ancient China, and also forward in time to 2025 (where he makes an alarming discovery).
Flight of the Phoenix by R.L. LaFevers is the first book in a new series called Nathaniel Fludd, beastologist. Sent to live with a distant relative who is a beastologist (a person who studies beasts, I suppose), Nathaniel must travel to Arabia to protect the last known hatching phoenix egg. Then his cousin goes missing, and Nathaniel must rescue him, and save the egg… a tall order!
