Angelbound Origins Collection: Books 1-5 by Christina Bauer is free.
This is an indie series, of which I've read and enjoyed three of the books (
Angelbound and
Scala that are in this omnibus and
Armageddon that isn't). The series is YA contemporary fantasy that's well written and fun to read. By way of testimonial, I originally got Angelbound for free, then paid for
Scala and
Armageddon, which were the only other two in the series at the time. The author has apparently written a number of other books since and rearranged the series order.
