For eighteen straight summers, Violet and Will were inseparable at her family's beach house on the Maine coast — until a tragedy broke the pattern and kept them apart for five years. When Violet returns, reluctantly, to handle the sale of the property, she finds Will still living nearby, and the unresolved history between them refuses to stay in the past.
Perkins builds the novel around the accumulated weight of shared history — eighteen summers' worth of memory compressed into a single reunion — and uses the beach-house setting to keep both characters physically confined to a place saturated with what they lost. The tragedy that separated them is treated with real weight rather than as a plot device to clear quickly.
The Infinity Between Us is a second-chance contemporary romance built on long-term emotional intimacy and unresolved grief rather than a fast-moving plot.
