Between Us by Amabel Daniels

Starting a new job is stressful enough. Yet, on day one, security guard Aaron Boone is beyond panicked when he realizes his charge for the next few days is the gorgeous blonde he slept with the night before—who seems to be his boss’s wife. So much for an innocent one-time fling. She insists she’s not a cheater, but regardless of an epic misunderstanding, he’s determined to at least see to his duty and finish the assignment. If only it could be that simple.
Felicia Arlon isn’t just a stand-in fiancée for an old friend. She’s a successful influencer, about to finish a long-running challenge benefiting a worthy charity. With a few days to completion, she’s delayed while she heads off to a solo “honeymoon” in Kauai.
She’s not alone, though, with her one-night stand tagging along, making her wish for things she can’t have.
Can anything positive come from the forced proximity of two strangers—with the lies and assumptions standing between them?
