Harriet Turner knows all about journeys. After all, she's arranged hundreds of them for the travel agency her family runs in the Australian coastal town of Merryn Bay. But when her work colleague and foster sister Lara disappears on the eve of a big overseas trip, Harriet finds herself in uncharted territory.

Left alone in England with a coachload of eccentric tourists on a themed tour of locations from the Willoughby TV detective series, Harriet has her hands full. But as the bus trundles through the picturesque Cornwall countryside, the tour becomes another kind of journey for her. She finds herself facing big questions about her family and her childhood, about her feelings for the guest of honour on the tour, star of Willoughby, Patrick Shawcross - and the biggest puzzle of all: what has happened to Lara?

Praise for The Alphabet Sisters

'Big-hearted family saga set in Australia, Ireland and London'

DAILY EXPRESS

'Tender and well-observed...there is also plenty of McInerney's trademark wit, but have the hankies ready for this, probably her best novel yet.'
