Herb-Wife. Lord Alchemist, #2

The Lord Alchemist must be immune to hostile potions. But in all of Cymelia, there are only three with the alchemist's immunity: Iathor, his brother Iasen, and the half-barbarian herb-witch, Kessa. Though Kessa is hardly the expected wife of a noble, Iathor has secured a betrothal - but his brother has vowed to prevent the marriage by any means necessary. Iathor will do whatever he can to keep his wife, no matter what she's done or what his brother tries, but Kessa's own dark secrets may sabotage any hope of a happy ending.(This sequel to Herb-Witch contains mature scenes.)
