The author of Astrid and Veronika discusses and signs her latest title, Sonata for Miriam, today. Linda Olssons debut novel, Astrid, was extremely well received, and fans anxiously awaited Sonata. It seems the wait was worth it. The story takes readers to Poland, New Zealand and Sweden, as protagonist Adam Anker searches for the truth about his parents fate during WWII. Not fun, lighthearted stuff, but certainly an engrossing read. 7 p.m. Blue Willow Bookshop, 14532 Memorial. For information, call 281-497-8675 or visit www.bluewillowbookshop.com. Free.
