Practice made perfect.

Suddenly finding herself a foster parent shakes things up for Dr Violet McCabe. Especially because her attractive and pragmatic colleague, Dr Gavin Monroe, is baby Ava's co-guardian. Together they must work to find Ava the perfect adoptive family.

Gavin secretly crushed on Violet for years, but after losing her fiance, Violet's heart was impenetrable - until Ava changes everything. But in their search for a perfect home for Ava, will Violet and Gavin miss that the best family for her is the one they've already created?
