Highland Strength by Celeste Barclay

A lonely woman with far too many secrets…
Greer Gunn feared for her life every day that she breathed the same air as her father. An unwanted reminder that he had no heir, Greer employed her greatest defense. She looked and learned, tucking away her clan’s secrets that she used silently to defend her people against her father’s inept leadership and to keep their enemies at bay. When her father’s death leaves her adrift among a clan that no longer wants her, Greer turns to her longtime friend for shelter. But it’s her friend’s brother who plagues her every waking and dreaming moment. Can Greer put aside the secrets she shares with him and find happiness with a man who was once her adversary?

A man locked in his memories…
Thormud Sinclair, future heir to the almighty Clan Sinclair, finds himself once more entangled with the beautiful but elusive Greer Gunn. Their past is one no one knows about, and one they both wish to forget. But that’s impossible when it was Greer’s uncle who slayed Thor’s best friend the first time they rode out to battle. Events surrounding that fateful day continue to divide them while ghosts from their pasts push them together now. A decade after losing his friend, Thor stands to lose even more to Clan Gunn. His heart. Can Thor put aside the memories he shares with her and discover whether fate truly had something else in store for them?

A threat and questionable honor…
When some secrets just won’t remain buried, a threat to Greer’s life leaves this pair with little choice but to get along. Events beyond their control call Thor’s honor and loyalty into question. While being forced together might turn these enemies to lovers, will the encroaching danger allow these tortured souls to find peace?
