Water Damage- Touch Screen Unresponsive

Hello :) I left my Kindle Voyage in the rain (devastating)! After a few days in rice I plugged it in and turned it on. To my surprise- it turned on and lit up. However, the touch screen isn’t working. The side buttons still vibrate and work, I just can’t select a book or anything because the touch won’t work. Is this something that is fixable? Or is it gone forever? Thanks!
