Revenge is best served pre-ordered. How to Destroy Your Ex, the wickedly funny new novel from Jenny Morris, is available for pre-order now.

How to Kill Your Family meets The Husbands in a darkly funny, wickedly original novel about friendship, revenge and the dangers of playing God.

Thea has a gift. Or possibly a serious ethical problem.

With a single touch, she can see exactly how long someone has left to live. She can also take that time from them and give it to somebody else.

She discovers this when her best friend Ruth suffers a fatal head injury on a night out. Panicking, Thea grabs the man responsible. Ruth wakes up. He falls down dead.

Now Thea has the power of life and death at her fingertips - and she is determined to use it responsibly.

Mostly.

Because surely her dreadful boss can spare a few months. And doesn't the masseuse who finally sorted out her shoulders deserve a generous tip?

To keep herself on the straight and narrow, Thea writes an Ethical Guide to Murder: rules governing who deserves to lose time, who deserves to gain it and how to make the world just a little bit fairer.

But justice is complicated. Revenge is tempting. And absolute power is alarmingly easy to justify.

As Thea's rules begin to unravel, she must decide who she is willing to kill - and whether she can save Ruth before her borrowed time runs out.

Murderously funny, sharply observed and unexpectedly moving, An Ethical Guide to Murder asks how far you would go for the person you love - and whether anyone should have the power to decide who deserves more time.

'A marvellous debut! Jenny Morris has taken the "with great power comes great responsibility" concept and applied it to someone who struggles to be responsible for her own laundry'
