Sam’s Secret by Ivy Myst

Dr. Chloe Parker thought she knew everything about the man she loves. She’s even found the engagement ring receipt hidden in Sam Mitchell’s office and starts planning their wedding while she waits for his proposal. But when a woman from Sam’s past arrives in their small town, Chloe’s perfect world begins to unravel.
Mysterious phone calls. Unexplained absences. Large cash withdrawals. The man who once shared everything with her is suddenly keeping secrets, and Chloe can’t shake the feeling that she’s losing him.
When the truth finally comes out, Chloe must decide: is love strong enough to survive the secrets that came between them?

Trigger warning – there is no cheating in this book but it does contain other woman drama, perceived cheating (because of the said OW), child abandonment and a veterinary emergency involving animal loss.
This is book 2 of 3 in the Willowbrook series. Both published books can be read standalone.
