Molly Shannon

Add “Saturday Night Live” alum and actress Molly Shannon to the list of celebrity children’s authors. Shannon will be at the Barnes & Noble in Tysons Corner Monday afternoon to read from her new children’s book, “Tilly the Trickster,” about a mischievous little girl who plays tricks on everyone she knows. Might Tilly be based on Shannon’s girlhood? You’ll have to ask her, because — let’s be honest — while your kids are sure to love “Tilly,” you’ll be right there in line with them for a chance to chat up the book’s lovable author.

Monday at 4 p.m. Barnes & Noble Booksellers, Tysons Corner Center, 1961 Chain Bridge Rd., McLean. 703-506-2937. Free.
