Stay where I can see you : a novel / Katrina Onstad.

The Kaplan family has just won 10 million dollars in the lottery. But haven't they always been lucky? Gwen thought so. She's carefully curated a perfect suburban existence with a loving husband and two children. For over a decade, she's been a stay-at-home mom, devoted to giving her kids the quiet, protected adolescence she didn't have. But the surprise windfall suddenly upends the family, allowing them all to dream a little bigger and catapulting them back to the city that Gwen fled years ago. As the Kaplans navigate the notoriety that the lottery brings and try to adjust to their new lives in the upper class--Seth launches a dubious start-up, Maddie falls headfirst in love at her elite prep school--a tightly held secret is unlocked. Along with the truth come long-buried memories from Gwen's troubled youth, forcing her to confront her painful past and threatening to unravel the incredibly tight bond between her and Maddie. Her meticulously constructed identity as the good wife and mother begins to crack. And when their changed circumstances place her family under threat, Gwen must wake up from her domestic slumber.
