Rules at the School by the Sea: The Second School by the Sea Novel (School by the Sea, 2)

It’s summer, but school is in session in the delightful second book of New York Times bestselling author Jenny Colgan’s utterly charming School by the Sea series, set at a girls’ boarding school in Cornwall.
For the second year at Downey House, it's getting harder and harder to stick to the rules . . .
Maggie Adair’s first year as a teacher at Downey House was a surprising success. After making the leap from an inner-city school in Glasgow, she’s learned to appreciate the mellower pace of the girls’ boarding school by the sea.
Now engaged to her longtime boyfriend, sweet and steady Stan, Maggie’s just got to stop thinking about David McDonald, her colleague at the boys’ school down the road. Well, hasn’t she? Can Maggie take a leaf out of the Well Behaved Teacher’s exercise book and stick to her plan for a small but elegant wedding and settled life of matrimony?
Even as Maggie tries to stay within the lines, rules are being broken all around her. Maggie’s boss, headmistress Veronica Deveral, has more to lose than anyone. When Daniel Stapleton joins the faculty, Veronica finds herself forced to confront a scandalous secret she thought she’d carefully buried forever. How long will she be able to keep her past under wraps?
What does a new year of classes, rules, and camaraderie hold for the students and faculty at Downey House?
