Tanglewood Magic by Genevieve Jack

Her magical strength is transformation, but is she powerful enough to change his heart?
A witch in the crosshairs
Circe Tanglewood has tried to fit in with the other witches of Darnuith, but since the day her sister became queen, she’s been the target of painful rumors and vicious threats. Aside from her sisters, her only friend is the owner of the apothecary where she works. Her heart wants more from the taciturn and commanding Rhys, but she’s hesitant to risk losing her sole ally.

A wizard with a past
Rhys Bloodgood has suffered loss and never plans to open himself up to it again. No matter how attracted he is to Circe, allowing himself to love her is a gamble he’s not ready to take. Besides, a failed relationship might lose him a talented apprentice.

A war that will either bring them together or tear them apart
Rhys and Circe must work together to save Queen Medea from a poisoning attempt, which shatters the walls between them and drives them into the mounting political turmoil between Darnuith and Paragon. When friends become lovers, there’s nothing like the magical high, but the perils of finding Medea’s would-be assassin could destroy them before they have a chance to begin.
