Rescue and Rage: Madelyn of the Sky, cartea 4

How can there be a second Madelyn of the Sky?

Madelyn has set out to rescue those who need her help. She's ready for a little adventure, and her floating Island in the sky provides them a new home.

But someone else has started rescuing refugees first-someone very much like Madelyn herself.

Who is this other Madelyn? Where did she come from? And has Madelyn finally met someone who will wipe away her cocky smile?
