Keeper of the lost cities

At age twelve, Sophie learns that the remarkable abilities that have always caused her to stand out identify her as an elf, and after being brought to Eternalia to hone her skills, discovers that she has secrets buried in her memory for which some would kill.

Sophie's talents are getting stronger and, with the elusive Black Swan group ignoring her calls for help, she is determined to find her kidnappers but a daring mistake pushes her world to the edge of war, and soon she has exposed a major conspiracy that could threaten all she loves.

"Sophie Foster is back in the Lost Cities--but the Lost Cities have changed. The threat of war hangs heavy over her glittering world, and the Neverseen are wreaking havoc. The lines between friend and enemy have blurred, and Sophie is unsure whom to trust. But when she's warned that the people she loves most will be the next victims, she knows she has to act. If the Lodestar Initiative was the Neverseen's version of Project Moonlark...did that mean...

"After the Neverseen prove how vulnerable she is, Sophie decides to learn how to fight, but battle training won't help her friend facing a different kind of danger." --

With her friends divided and scattered, and the Black Swan wanting her to focus on their projects, Sophie is led in a different direction to Stellarlune, which might be their salvation or destruction, and learns the true meaning of power--and evil.

The past and present unravel into staggering truths in this can't-miss installment of the New York Times and USA TODAY bestselling Keeper of the Lost Cities series told entirely from Keefe's point of view.
