Lori Foster’s Firefly Summer series captures the feel of long, lazy days by the water. The Guest Cottage kicked things off in 2025, and The Lake House follows in 2026. Both books are set in a lakeside community where the pace of life slows down and the characters have room to figure out what they really want.

This series leans a bit more toward women’s fiction territory than Foster’s earlier category romances. The setting plays a big role, and the stories balance romantic relationships with personal growth and the kind of friendships that form when people step away from their regular lives for a summer.
