*"This savvy, insightful take on the modern family makes for nearly nonstop laughs."—Kirkus Reviews, StarredStewart, 13: Socially clueless genius. Ashley, 14: Popular with everyone but her teachers Ashley's and Stewart's worlds collide when Stewart and his dad move in with Ashley and her mom. The Brady Bunch it isn't. Stewart is trying to be 89.9 percent happy about it--he's always wanted a sister. But Ashley is 110 percent horrified. She already has to hide the real reason her dad moved out; “Spewart” could further threaten her position at the top of the social ladder. They're complete opposites, but they have one thing in common: they—like everyone else—are made of molecules. In this hilarious and deeply moving story, award-winning author Susin Nielsen has created two narrators who will steal your heart and make you laugh out loud. Praise NCSS-CBC Notable Social Studies Trade Books for Young People Nominated for the George Peach Book Award for Teen ReadersNominated to the Pacific Northwest Young Reader’s Choice AwardTexas Lone Star Reading List"A laugh-out-loud story of two teens learning to adjust to unusual family life that neither expected...Everyone from teenagers to adults will enjoy this story of ups and downs, laughter and tears, and the healing power of love."--VOYA*"Drama, humour, poignancy, and suspense are rarely found in such perfect proportions..some truly funny writing...stellar, top notch stuff."—Quill & Quire, Starred What Other Authors Are Saying“Susin Nielsen is one of the best writers working today.
