The Invisible Life of Addie La Rue by VE Schwab is on my tbr list and is itself using The Time Travellers Wife as a comp title ( and Life After Life by Kate Atkinson). Published this year.

I loved that book but I wouldn't say it was a romance.
Shame for Iren's purpose. Looking forward to reading it, though
This looks really good, just my type of read, and it may do for a comp, so very many thanks :)
