A Sixth Sense of Forever: Book Three of the Forever Series

The Malone brothers ask their best friend Boz, the Duke of Sedgewick, to teach their sister Lily about sex. Boz has secretly loved her for years but his family is burdened by a dark faerie curse - If a Sedgewick weds for love, his bride will die before birthing a child. Sedgewicks hide the curse behind the fiction that they do not fall in love. 

The favor Boz should refuse promises a taste of the forever he can't have with Lily. Surely he can teach her about sex, not take her virginity and still wed his cold, calculating fiancée. Can't he?
