Autumn’s Shadow by award-winning author Lyn Cote is my featured ebook, available today for free on Amazon Kindle. While it’s the second book in the Northern Intrigue series, I’m guessing that you could start with this book,  since it seems to have a complete story arc. Twenty-six readers gave it a composite of four of five stars on Goodreads.

Here’s the publisher’s blurb on it:

Romance and mystery in a small Wisconsin town.

Someone has a mean sense of humor. And is springing nasty pranks at the local high school. Who and why? And more importantly how can Keely Turner, the principal, and Burke Sloan, a sheriff’s deputy, stop the malicious prankster before someone gets hurt badly? Keely, the daughter of the richest man in the county, and Burke, a newcomer with his own family baggage, are attracted to each other in spite of their intentions. The fact that her teen-aged brother and his nephew become enemies doesn’t help either.
In the midst of this, the mystery baby from Winter’s Secret, Book One in the “Northern Intrigue” series, remains unidentified. But soon Keely uncovers a clue that may lead to the baby’s mother. Will the baby return to her mother or remain with her adoptive family? But over all hang the bigger questions. Whose is the spiteful mind behind the increasingly dangerous pranks? And will Keely and Burke be able to shed the disappointments of the past and the present and breakthrough to love? Only God can answer that.
