Good for the first in a new series.  I'm a sucker for stories set in a coastal community, and a library set in a lighthouse is a cute touch.  The plot had a lot of twists and turns, kept me guessing until the end.  The secondary characters weren't fleshed out very well, mostly just one-dimensional scenery. Also a hint of a dreaded love triangle (ugh!) that I'm hoping is not long and drawn out.

Definitely a promising start and I look forward to reading the next book in the series.
