Paragraph using all five expressions

My sister has had her nose in a book all week because she got hooked on a new mystery series. Once she starts reading, she gets so absorbed in the story that she doesn’t hear anyone talking to her. Last night she was completely lost in a book for hours, and by the end of the weekend she had been reading non-stop.
