The Keepers (The Keepers Trillogy) (Volume 1) - J.L. Block

Although the action scene is very clumsily written, shockingly passive and boring, I really like that Ava isn't suddenly granted magical powers. I like how she knows how useless she is and uses that to her advantage. And I like that she gets hurt - she doesn't suddenly come into some magical power or all her training leads to her 'magically' being a good fighter. So all in all, a good sequence.
