This is a slow time for new releases. Things will pick up in June as the summer book market begins releasing books for the coming months. But for now, here are several you might enjoy.
Nina Rowan Dream of Desire
Madeline Hunter The Accidental Duchess
Karen Ranney The Virgin of Clan Sinclair
The last two are the third books in a series by each author, but can be read as stand alones if you haven't read the others.
