The elephant of Tusk Temple - Joshua Davidson

When Will accidentally creates a mysterious portal during a trip to the zoo, he's transported into the world of the Night Zoo, and thrust into an incredible adventure. Joined by his friends, Sam and Riya, Will journeys through a new portal and arrives at the Tusk Temple in search of Maji the time-travelling elephant. But the temple is in danger. The only way to save it is for Will to undergo the Night Zookeeper trial - facing leaps over bottomless caverns, impossible puzzles, and an ultimate test in bravery. Can Will pass the trial and save the day, or is this the end of the Night Zoo?
