Splitscreen: Attach of the Soul-Sucking Brain Zombies and Bride of the Soul-Sucking Brain Zombies

Split Screen by Brent Hartinger - two books in one tell stories of gay teen romance (some romance for the guys, and some for the ladies) --which is already lovely, and then everyone stars as extras in a zombie movie....which is hilarious.
Plus, I first heard of this book from an UNSHELVED Sunday Book Club comic. You can see it here.
I checked it out. 287 pages.
