Obernewtyn Chronicles, Books 1 & 2 by Isobelle Carmody (Paperback)
The Obernewtyn Chronicles, Book 1
In a world struggling back from the brink of apocalypse, life is harsh. And for Elspeth Gordie, it is also dangerous. That's because Elspeth has a secret: she is a Misfit, born with mysterious mental abilities that she must keep hidden under threat of death. And her worries only multiply when she is exiled to the mountain compound known as Obernewtyn, where—for all her talents—Elspeth may finally and truly be out of her depth. Then she learns she’s not the only one concealing secrets at Obernewtyn.
The Fairseekers : Obernewtyn Chronicles, Book 2
Since their takeover of Obernewtyn, the secret community of Misfits has flourished, protected by their remoteness. Led by Elspeth Gordie, whose extraordinary powers set her apart even among her Misfit friends, an expedition sets out to rescue a powerful Misfit in a distant part of the Land.
Only she knows the enormity of their task. But for her there is yet another challenge, as she must fulfil her vow to find and dismantle the dormant death weapons left by the Beforetimers.
