On the hunt! Part 2

I'm still no closer to finding the only book I never finished. I remember I was reading Randy Powell's "Is Kissing A Girl Who Smokes Like Licking An Ashtray?" just before so I thought maybe he did a collaboration with his wife, but I can't find anything to suggest he did. Then the name Melvin sprung to mind again so I checked out another teen fiction writer I was into at the time - Melvin Burgess. Now I'm convinced it was a collaboration he wrote with someone but I've had no luck with that theory yet. I've even searched for books he may have wrote with Randy - but nothing. So the hunt continues...
