The reason I'm rambling about this is because I'm working on my latest novel (I shelved the Cuckoo series because it's still being evil to me and am 20k into this one in a week. Gah). Its title is CALLED, which I rather like, but I don't know if it really grabs at you and makes you want to look at the book.
It has got me thinking about books I've read in the past where the title really hooked me. ONCE UPON A GARDEN HOSE is a kids' book with a great title, it really is. My favourite title though, so much so that I remember it decades later, is a book titled OUTNUMBERING THE DEAD. I don't remember who wrote it or what it was about, but I remember that title. I wish I'd thought of it. I'd have written a book around that title.
So what is your all time favourite book title? I'd love to get a list going in the comments.
