Confessions of a Highland Assassin by Shona Thompson

She had to take away his last breath only to end up being the one with a crashed heart in the end…
Ava Rose is an assassin for hire. But even when taking other people’s lives, she has vowed never to put an innocent soul under her blade. Until her brother is kidnapped, and she is forced to accept a perilous proposition. Kill the infamous laird, Boyd Cameron.

But there’s a catch – she has to make him fall in love with her first…
Boyd Cameron had lost everything when his betrothed was abducted the night before their wedding. Yet, even dreading the idea of getting wed again, he cannot postpone the wishes of his council any longer. Thus, he organizes a ball with a slew of lairds’ daughters, which Boyd is sure he’ll detest.

Until he falls under the spell of the mysterious Ava whose family he doesn’t even remember inviting…
And, as Ava’s mission becomes increasingly challenging, for she must choose between saving her brother’s life and murdering the man she has fallen for, she neglects a critical matter; the identity of the man who hired her…
She had one simple task – make him fall in love with her and then… kill him.
