For those who didn't grab it the first time it was on sale but are interested after apesmom and I recommended it, Sweet Filthy Boy by
Christina Lauren [book 1 of Wild Series] is on sale again for $2.00.
I linked her whole page because the first of her other series [Beautiful Bastard] is on sale for $.99 and book 2 for $2.99. IMO book 1 of that series was only a 3 star read, but as I posted earlier the rest of that series was rated much higher.
