Impact Zone by Keira Andrews

A forbidden vacation hook-up years in the making... of course it means they're going to cross paths again...

From the blurb:

One forbidden night with his best friend's father.

Lifeguard Lachlan Yang hasn't thought about his harmless little crush on his best mate's dad in forever. He hasn't even seen Tim Bullock in fifteen years.

Then they walk into the same bar in Bali—and Tim doesn’t recognize him.

Lachlan should confess who he is. Of course he should! But Tim moved away from Barking Beach years ago and is estranged from Lachie’s best friend, Ryan.

They're never going to see each other again. And Lachlan hasn't wanted anyone this much in a long, long time.

It'll be his secret.

Until he comes face-to-face with his new boss at the beach…

Impact Zone is a steamy M/M romance by Keira Andrews and the third book in the Lifeguards of Barking Beach series. It can be read as a standalone, though you’ll definitely want to read every book about this found family of lifeguards saving lives and risking their hearts. This forbidden romance features an age gap, best friend's dad, demisexual awakening, bisexual identity exploration, and of course a happy ending.

Heather's Review:

I'm a sucker for best friend's father.. and this one was a delicious, hidden relationship, push and pull... I loved being  back at Barking Beach and watching Lachlan get what he's always wanted...  although I have to say some of the background story noise got in the way at times.  The layering of both Tim's and Lachlan's past traumas, the work environment and Ryan were a little overwhelming to read at times... but I was invested in the story and it was so worth pushing through!

I can't wait to see what happens next with Mark's story!
