The Tower of Nero by Rick Riordan

The Trials of Apollo. Penguin Random House, 2020. ISBN: 9780141364087.
(Age: 11+) Recommended. In a return to Percy Jackson's world, Apollo - in his human form as teen, Lester Papadopoulos - must go into the final battle against the opposition of Nero and his extreme power, to enable Apollo to return to Mount Olympus. The fight is also against every awful and mythological enemy that has come under the power of the last emperor Nero. Meg is at his side and she is trying to overcome her history as Nero's adopted daughter while being Lester's 'Master' in the fight. The engagement of oracles, underground troglodytes and other demi-gods all work together to assist Lester (Apollo) to finally face the worst of the conflicts, but there is wounding, fear and the possibility that Apollo may lose his challenge and be trapped in human form without the opportunity to return to his godly form . . . and does he even want to give up his humanity?
In the world of Greek Mythology and the Percy Jackson series, this is a concluding story in the Trials of Apollo. Although it would best be read after the preceding four episodes of the trials, it is not impossible to read without prior knowledge. Fortunately, there is a glossary to explain all the mythology terminology and creatures. Rick Riordan has been able to introduce young readers to ancient mythology through his exciting quest and battle scenarios and they love the 'fantasy' elements and the adrenaline-charged action. With Haiku to foreshadow each chapter and fast-paced writing, there are no dull moments. Needing some maturity to deal with the aggressive combat within the myths of ancient worlds, this is best suited to readers aged 11+. But they will love the action! Themes: Mythology; Action/Adventure.
