Under a Dark Sky by Lori Rader-Day

She's still lost after the death of her husband.  She decides to go on a trip he had planned before his death.  That was a mistake...

Wm Morrow and Edelweiss let me read this book for review (thank you).  It will be published August 7th.

She anticipates a guest house where she can put the past to bed and move on.  Instead, she finds out she's sharing it with another group and she has a separate suite.  She almost goes right back home.  She should have.  This is a deadly group...

Everybody in this group were friends in college and this is a reunion for them.  They all have secrets, nothing is like what it seems and there is a dead body the first night.  They try to blame it it on her but she doesn't even know them.

With secrets from her husband's past and a killer among them, she better come to terms with things soon or she'll end up being a victim, too...
