I went through all of my books at Harlequin's site. There were a few no longer in my library there, like the freebies I got from their 60th anniversary.
It was time consuming, but I'm glad I double-checked as I found 7 freebies I had not downloaded. Actually there were more than that, but I only downloaded 7 of them

None were urgent reads, but I plan to add them to Calibre and my TBR albeit in the maybe/possibly/someday category.
