Cathy Gillen Thacker’s The Harrigans/Birth Order Trilogy is a three-book fiction series from the late 1980s. One Man’s Folly and Lifetime Guarantee both appeared in 1989, with Meant To Be following in 1990 to close out the trilogy. The dual name hints that the series follows the Harrigan family, with each book focusing on a different sibling based on their birth order.
This is a compact series that readers can finish quickly, and starting with One Man’s Folly is the way to go since the Harrigan family connections carry across all three books. Thacker was a prolific author during this period, and the trilogy fits the family-centered romance style she was known for at the time.
