Keep your friends close and your enemies closer.
Cara shouldn’t have survived the attack.
But at the last moment, a stranger snatched her to safety.
In the hours that followed she told this Good Samaritan secrets she’d never told a soul.
Not even her husband . . .
In the aftermath, Cara is home, healed and safe.
Which is when the anonymous threats begin.
Someone knows things about her they shouldn’t.
Cara’s Good Samaritan offers to help her – to save her all over again.
That night Cara made a friend for life.
But what if she isn’t a friend at all?

Your Closest Friend by Karen Perry is one of those books that has you suspiciously evaluating relationships with some of the people in your life.

Strangers to each other, café-worker Amy and radio producer Cara are caught up in a terrorist attack in London, Amy literally pulling Cara out of the line of danger.  Caught up in the moment, fearing for her life and blind to what is happening outside or whether she will survive this,  Cara reveals more of her secrets to Amy than she has to anyone else – including her husband. Amy is more than willing to listen and the seed of an obsession is sewn. Eventually, the danger is over, the gunman contained and the two women go their separate ways, Cara a little embarrassed at the secrets spilled, but no harm done. Or so she thinks…until a short while afterwards, Amy reappears in Cara’s life, and the real nightmare begins.

This is a twisty, turny book bull of surprises and shocks, and you’ll be shouting at Cara at times. For an intelligent woman, she seems to ignore   blatantly obvious signs that Amy is not quite what she claims to be, but then most of us have been in a situation where we aren’t sure if someone is behaving oddly, or whether we’re just overreacting. Some of the situations that she questions internally could make her seem ridiculous & paranoid if she actually brought them up, and on thin ice with the people around her already (who are all falling for Amy’s sweet little act), you can believe she’d not want to push the issue.  Amy is a classic psycho, you can almost smell the crazy coming off the pages as you read.

The chapters are told in Amy and Cara’s voice, alternating from one to the other, which is a nice device as you get a real feel for the menace coming from Amy, and the paranoia developing within Cara. The effect on Cara’s home and professional life is devastating, and it’s creepy to see how Amy is always on top of what’s happening, twisting it to her own ends.

‘Your Closest Friend’ is a great, creepy read and will definitely have you watching who you tell your secrets to in future!
