Which book has made you lose track of time?

I usually listen to audiobooks a bit in bed before I go to sleep. I normally go to sleep around midnight, but the other day I was listening to a book, checked the time, and realized it was already 1.30 AM! I quickly turned off Audible, took off my headset, and went to sleep :)

That made me wonder what audiobook has made you lose track of time?, Have you ever been so absorbed in a book that you forgot to go to sleep, were late for your parents' wedding anniversary dinner, or even forgot to pick up a friend at the airport because you were completely caught up in an audiobook?, I'd love to hear your stories and find out which books were responsible :)

For me, the book was The Wizard's Cat by Nathan Lowell. It's not a book packed with drama or action, but somehow I can listen to it for hours. I think a big part of that is the narrator, Tom Taylorson, who has such a nice and pleasant voice :)
