The Martian by Andy Weir
Ready Player One by Earnest Cline
The Ice Cream Queen of Orchard Street by Susan Jane Gilman
So, if they don't grab me right away, I close it and pick up another. I don't get frustrated or feel bad, and I certainly don't press on reading a book in which I am not interested.
I remember this happening with a few of my favorites:
People of the Book by Geraldine March
Astrid & Veronika by Linda Olsson
I put those books down, and picked them up later. LOVED both of them. It just wasn't the right time to read them before, I guess.
So, reshelve your book if it doesn't grab you, with no guilt. You will pick it up, and maybe fall in love with it, later.
