International bestseller Khaled Hosseini (The Kite Runner) is a master of the sweeping story. He's back with his third novel, And The Mountains Echoed ($30, Viking), about orphaned siblings who are separated and live very different existences. The multi-character novel - some call it cluttered - spans generations and the globe, propelled by Hosseini's storytelling gifts and evocative prose. Launching alongside the book is The Echo Project (EchoProject.ca), a page-by-page digital companion. Hosseini signs books and talks to Heather Reisman at Indigo (Bay and Bloor) on Monday (May 27).
