What's the Story?

In the wake of Book 7's shocker ending, Sophie Foster is trying to come to terms with her LEGACY -- which includes being "unmatchable" with any potential elvin partner because her biological parents are unknown,and apparently want to keep it that way. This definitely puts a crimp in her budding romance with Fitz, while other love interest Keefe says it won't matter to anyone who really cares about her. Meanwhile, Sophie's got other things to deal with as the evil Neverseen rally their forces and enslave one of her friends, and she finds herself facing the challenges of leadership, enhanced powers, and new possibilities as the characters race headlong to another cliffhanger ending.

Is It Any Good?

Our review:
Parents say ( 7 ):
Kids say ( 46 ):

Book 8 in the Keeper of the Lost Cities series ups the ante with a raft of action, character developments, new magical powers, ethical dilemmas, world-saving, and teen romance. By now we're beginning to suspect that author Shannon Messenger has no intention of wrapping up the series in this lifetime, but that's not necessarily a bad thing. This year's doorstop-size volume brings a satisfying immersion in glitter, cosmic conflict, increasingly complex characters, teen anxiety, new magical powers, moral dilemmas, page-turning plot developments, and cliffhanger endings. Sophie and her friends battle evil, question authority, and struggle to do the right thing in impossible situations yet again, and many peripheral characters from previous installments make return appearances.
