Time For Love by Marie Force is currently free.
This is book 9 in her long-running Gansett Island series. Book 1,
Maid For Love is on perma-free. I'm very excited because the later books are never on sale, and this is where I left off in the series.
I don't necessarily recommend jumping in here as each succeeding book continues with side stories on previous characters and I think you'd be lost if you hadn't read at least a few of the previous books.
