[PREORDER] Margin of Error

By: Rachel Lacey

Release Date: February 3rd, 2026

From Rachel Lacey, author of Learning Curves, comes a tender, hopeful romance about how fate is what you’re given but love is what you choose, and how small sparks can change everything.

Two years after an accident in Manhattan almost claimed her life, Marin is determined to take advantage of her second chance. She’s left her husband, her job, even her home to pursue the life she’s always wanted. Now she’s teaching statistics at Northshire University and preparing to do something she’s spent decades dreaming about: date a woman. But the last woman she expects to encounter on her journey is the one she’s been fantasizing about since their chance encounter the morning Marin nearly died.

Charlotte has made big changes in her life since that fateful day too. Most importantly, she’s moved back to her Vermont hometown, determined to finally solve the thirty-year-old mystery of her mother’s disappearance. An unexpected―and unexpectedly intense―friendship? That wasn’t in the plan. Neither was questioning her sexuality, but the more time Charlotte spends with Marin, the more she realizes her feelings run deeper than friendship.

Surely this would be a disaster, both of them being each other’s first, except the chemistry between them feels too strong to deny. But as they get to the heart of the mystery―and the heart of who they are―what brought them together just might tear them apart.
