First off I'll say, I didn't enjoy it as much as her other novels. But that being said (and the 3 star rating), I did like it.
Molly and Daniel are both in trouble individually and instead of confiding in each other as a married couple, they try to figure it out on their own.
Liza witnesses something she can't quite figure out ( did she really see what she saw) and rushes (12 hour drive) to her friend, Molly.....saving her own life in the process as she comes back to her building gutted from a fire.
Liza and Molly have been the best of friends since college but have drifted apart over the last few years. Molly shuts Liza out after she runs to her. But they eventually get back to being friends.
