Claws for Concern by Miranda James

Charlie loves his new grandson and between volunteering at the library and then babysitting, his life is full.  Diesel helps him with the babysitting.  He's always loved the library so it's no hardship.  When he sees a new patron, he thinks he looks familiar, but he's no one he knows.  Then he finds out that they are related...

Berkley and Net Galley allowed me to read this book for review (thank you).  It will be published February 20th.

Discretely working around what he's been told by the man, he finds that his uncle, who had been briefly married to another woman before he married his aunt, had had a child with the first woman.  She didn't tell him.  When he finds out where the man is living, he thinks he should probably let the man stay with him.  His aunt would have.  But first he wants to make sure he won't bring trouble with him.  Unfortunately, he has been involved with law.

Twenty years ago, a whole family was killed.  He was accused of being the killer but there was no proof.  Everyone involved with the case is keeping their silence.  But when someone tries to kill the man in town, Charlie gets involved.  Something is going on with the cold case and he wants to get to the bottom of it.  He still can't learn anything from the man, so he starts trying to track down other people familiar with the case.

This is the tale of dysfunctional family that finally blew up.  The facts were put together almost backwards, so it's hard to sort out.  It's a good thing Diesel can set him straight.  Charlie comes close to death himself.  

It's a good read with Charlie, Diesel, and his loving family around him.  It's funny what people will do in high stress situations.  Then they pay their whole life for it.  Read it as a cautionary tale...
