This book is THE BEST highland friends to lovers romantic suspense historical romance I've ever read! As friends, Blair and Hardi's is so cute together and as lovers, their chemisty is sizzling and their love scenes are super hot (so this is a warning. If you want to read a clean romance, please skip this series. But for me, I love the series so much.) And Barclay created an intrigued and interested suspense plot that I hardly guess who is(or are) the betrayal(s). Can't wait for reading about Lachlan and Arabella's story next!
