Broken Sword by Kim Loraine

A love triangle made legend…A chance to rewrite the stars.

Lancelot:
I spent my life in service to my king, loyal to my queen, and loved by them both. Until she ruined me.
Guinevere made her choice and it wasn’t me. So I sought out a way to fight the pain of losing her…of losing them both. Eternally languishing in purgatory was not what I had in mind.
But now, hundreds of years later, I’ve been returned to life for a reason. The end times are here, and I’m the one chosen to help stop the apocalypse. I only wish the woman I’m bound to wasn’t the very one I’d tried to forget.
My Gwen had a secret she never shared in our past life together. She’s a witch, cursed to live forever, and she’s never forgiven me for what happened between us.I am Lancelot du Lac. I was her champion once, I will be again, and this time, I won’t so willingly share.

Brooks:
I never wanted to share Gwen, not with anyone, and definitely not with Lancelot. But now that he’s gone and the truth about my past has been revealed, everything is different.
I used to be a king. I lived my life shrouded by a lie. Afraid to take the love I desperately wanted—love from my queen as well as my knight. That fear is the reason I lost both of them. This is my second chance to be the man Gwen needs, to take up Excalibur and stop the apocalypse, and to finally accept who I truly am.I am Arthur Pendragon, at least, I was. In our past I broke both Gwen and Lancelot. But this time, I’ll be the hero they each deserve.
