YA or Romance book where the two main characters meet again because the guy needs the help of the girl with his niece or nephew

So I’ve read this book’s synopsis a few weeks ago and I forgot the title of the book! I also wasn’t able to add it to my goodreads shelves. What I I can remember about the synopsis is that the guy and the girl meet again and the guy needs the help of the girl because of what his niece/nephew did. I think the girl is a lawyer or something. I also think the book was just released a few months ago but I am not sure. Please if anyone knows the title please let me know I’ve been looking for it since last night on twitter and IG but I can’t find it! And I really want to read this book! Thank you!

RiaLyn, about how old is the niece/nephew? Is it a custody or criminal case?

What's the tone - e.g., romantic, romantic suspense, mystery, angsty, steamy/clean, funny, sad/somber?
