Great! Glad you found it again. I'll move this thread to Solved for you. :)
Cassie Binegar matches some elements: young girl feeling out of place in her big, loud family and a close relationship with her grandmother. Don't know about the rest of it, though.
The Raising for the link to Megan's suggestion, which does seem to be a better fit. (And sounds really good. Adding it to my TBR list.)
From the Mist for the GR link to Sherry's suggestion

It's unlikely to be a YA series if both of the protagonists are adults. Could it possibly the
The Time Traders series by Andre Norton?
The Widows' Adventures for the GR link. Lynn, is this your book?
Through to You, maybe? Although it's YA, not adult fic, the cover and plot seem to fit.

Yep, me too. My mind keeps going back to the Julia Redfern books by
Eleanor Cameron or something by
Norma Johnston but I don't think either of those are it.

You're welcome! Happy to help. :)

The Fetch by Laura Whitcomb
One Fat Summer for the GR link to bookel's suggestion

Maybe
The Hideout?
Feeling unloved by his mother and new stepfather, Andy hides out in a luxurious San Francisco hotel and stages his own kidnapping in order to obtain ransom money to pay for a trip to England to see his father.

Daniel, this sounds like a non-fiction book, is that correct?

Glad you found it, Jessica! I'll move this thread to Solved and add the book to our group shelves.
