‘Beautifully written. We loved it’ - Woman’s Way, Book of the Week ‘Hilarious’ - Irish Tatler Man ‘Hilarious debut’ - Irish Mail on Sunday ‘One of the year’s best debuts’ - Jennifer Zamparelli, 2FM

Sister Agatha is 118 years of age, whose vim and vigour would put the most robust athletes to shame. However, during a routine check-up, her doctor claims that she has just a week to live-inconvenient, seeing as the beloved sister once made an improbable vow: to be the oldest person in the world. At last count, she was the fifth. Never one to admit defeat, Sister Agatha concocts a bold Plan B. Using her final days, she intends on travelling the world to meet the only four people whose birthday cakes boast more candles than hers.

And then, one by one, she will kill them.
