Burke's new novel is The Better Sister.
One of the author's ten favorite thrillers about siblings, as shared at the Guardian:
Sister by Rosamund LuptonRead about the other entries on the list.
I was lucky enough to read an advance copy of this. I remember checking the jacket three times to make sure that it was actually a debut, because it was written with such confidence. When older, more reliable sister Bee goes looking for her younger, flakier sister Tess, she expects to find her off on her usual antics. Instead, she learns that Tess is dead, supposedly by suicide. Bee’s ensuing search for the truth is a moving and beautifully written tribute to sisterly love. It’s also got a jaw-dropping twist.
Sister is among Laura Jarratt's top ten YA thrillers with sisters and Sophie McKenzie's top ten teen thrillers.
