Winter Jacket is a May-December romance (the age gap is just 10 years so nothing shocking there) but it is compounded by the fact that the protagonists are a teacher and a student. Nothing overly unethical happens though, so no worries there. The romance is sweet. The development is slow and enjoyable. The sex is really hot. The characters were well-rounded, and sufficiently conflicted about their relationship, but willing to make a go of it. External pressures like parental disapproval and school politics provide some angst. Overall, an enjoyable read.
