I don't need the love of my childhood crush. With this plan, I'll find happiness on my own!

Tomboy Katie Malloy was neighbor to Sean Fitzpatrick and his brothers…and effectively an adopted member of their family. Kate and Sean have spent the past two decades as best friends, supporting one another in their various relationships and life goals. Now, as they near their thirties, Sean is a successful private investigator in business with his brothers. And Katie? She wants to have a child, and she has a list of potential fathers for Sean to investigate. While Sean will investigate three potential baby daddies, he just has to know whose were the other two names that Katie struck from her list. One was his brother with whom she broke things off. The other was Sean himself. Would Sean want to be the father of Katie's child? Katie's been like a sister to him all these years, but maybe their friendship has been hiding something more...
