Grace Trevethen, whose late husband jumped out of a plane without a parachute, has been left with a manor on the Cornish Coast – and the massive, suffocating mountain of debt her husband had been secretly amassing. Now, with creditors and repossessors on her heels, Grace is faced with the prospect of losing everything.

When Grace is asked to tend an ailing, if illicit, plant belonging to the manor’s soon-to-be-sacked caretaker Matthew, she gets the outrageous idea to use her renowned green thumb to make some serious money and pay off her debts? Working with Matthew, Grace transforms her orchid hothouse into a prodigiously lucrative enterprise of another kind.
