Disbelief (Michaela and Trisha Book 4)

When Trisha discovers that Michaela is planning a romantic weekend away, she's suspicious that Michaela is going to follow through on her threat to ask Trisha to marry her. She should be over the moon at the thought, but instead she's sick and scared.
Things are good just as they are, why change them?
Trisha's never felt she could cope under pressure, and marriage means lots of pressure - not to mess up ever again.
She agrees to the weekend trip anyway, but nothing goes as planned. Lost in the forest, Michaela badly injured, it's up to Trisha to be the strong one for once.
Or will she let her own disbelief threaten both of them?
