You have 2 options try your luck at the store you got it from or find a place that has a glue binding machine ( places that sell self made test completions to high school students tend to have it).
For the latter you gotta pick each page and remove previous glue as much as you can. They will take care of the rest.

If you recently bought it on a store and still has the receipt maybe you can exchange it? .Books are expensive.
