Small-town Steadfast, Wisconsin, has spent the last six years raising funds to help a medical student stay in med school. In return, the student contracted to practice medicine in the local clinic for the next six years. Kirsi Royston is that doctor, and now she must tell the town she is leaving at summer's end. Family responsibilities demand she return to California. She promises she'll find a replacement and all will be well.

Kirsi is a dedicated doctor and a dutiful child. Her counterpart, known as Dr. Doug, is the same. His father died young, and his eighty-something grandfather deserves to retire. In the midst of their conflict over Kirsi wanting to break the contract comes the unthinkable. Meth is creeping into the county, poisoning students at the local high school. And the local eccentric, a woman who has bullied the town for years, finds herself needing help. Kirsi wants to provide that—another reason for the townspeople to grumble.

But all is overshadowed by events. A teen nearly dies and then vanishes from the hospital. An anonymous dead body turns up. Summer's End is the story of two very good people, trying to please everyone but themselves. In the midst of a dangerous new situation in town, will they take a moment to discover what God wants for them?
