I'd probably rate this book lower if I weren't so familiar with Black's fairy world. There is comfort in re-experiencing characters. 

I commend Black for the noticeable change of tone when writing from Oak's perspective in this sequel, a change from the first book. It was different enough to believably be another character with a distinctive personality. 

However, this failed to really capture my interest. Oak is not a likable character, although we're supposed to root for him. Wren loses her personality completely, becoming one dimensional and more of a plot device. It was disappointing given she was a welcome change in the first book.
