This book starts with a bang in the two page prologue and then slows WAY down with maybe taking too long to give the background on the main character. However, if you can stay with it for the first 150 pages, after that, it gets good. And, once it shifts, it starts moving fast. It is almost like reading two novels in one.
Summary from amazon.com:
Since We Fell follows Rachel Childs, a former journalist who, after an on-air mental breakdown, now lives as a virtual shut-in. In all other respects, however, she enjoys an ideal life with an ideal husband. Until a chance encounter on a rainy afternoon causes that ideal life to fray. As does Rachel’s marriage. As does Rachel herself. Sucked into a conspiracy thick with deception, violence, and possibly madness, Rachel must find the strength within herself to conquer unimaginable fears and mind-altering truths. By turns heart- breaking, suspenseful, romantic, and sophisticated, Since We Fell is a novel of profound psychological insight and tension. It is Dennis Lehane at his very best.
