Last Chance for Her Rancher Boss by Holly Rayner

They were best friends once, then it all blew apart,
Ten years on, could this be the new start they both need?

Burned by young love that wasn’t returned, Meg Whitmore left her small Wyoming town and never looked back. That is, until a new assignment has her retreading old ground, and her new boss turns out to be the one guy she hoped not to run into…
Nash Callahan has had a long time to regret letting Meg get away. Now she’s back, and his future depends on working with the woman who clearly hates his guts. Meg does her best to put her feelings aside and be professional, but it’s clear that the years have done nothing to diminish the effect her former best friend has on her…
Soon the ice between them begins to thaw, and it becomes clear that the one-time class clown has found something he excels at. And selling the ranch isn’t a choice he’s arrived at lightly, but one that’s eating him up inside.

So much for ignoring Nash, Meg finds herself instigating a last-ditch effort to turn his fortunes around.
They can join forces to save the ranch, but can they ever find their way back to each other?
