The is the third and final book of the Beyonders series by Brandon Mull, Chasing the Prophecy (Lexile: 720; Interest Level: Grades 5-8), begins with our heroes (Jason, Rachel, Galloran and their friends) gaining their strength and planning at a secluded jungle retreat after having heard a prophecy that gave them a small chance of overcoming the emperor. The group splits into two, one taking Jason to seek the prophecy of Darian the Seer (who died over 1,000 years ago) and one following Galloran (and Rachel) to take back Trensicourt and prepare an army to attack Felrock.
Will the friends be able to complete the tasks set by the oracle? Will they be able to do it in time to defeat Maldor? How many friends would they lose along the way? I don't want to give away the ending, but I will tell you that this book is full of adventure, nail-biting close calls, and worry about making the right choices. You will definitely need to read this trilogy in order, starting with World Without Heroes. (506 pages).
One of the reasons I became an elementary school librarian is so I can read children's books.
