White is for Lilies (The Friends #3)
Kathryn Freeman

Kurt doesn’t take anything lightly, including relationships, so he’s learnt to keep his feelings for the flirty Sofia under a tight wrap. But when she’s targeted by a stalker, he can no longer sit back and pretend he doesn’t care.
As Kurt moves in with Sofia to help keep her safe, it isn’t just the danger from her stalker they are forced to face. Their sizzling attraction is about to make both their lives that much more complicated.
This is the third book in the Friends series. It can be read as a standalone but follows on from Red is for Roses.
