Infinite (Troyler Works Collection)

Includes the one-shot Kisses, summary as follows:

Troye's life can easily be documented by the kisses he gives and receives- like that gross girl on the playground when he was eight or that random guy at the party when he was fourteen. As he grows and changes and moves through life with more than a few crashes along the way, these kisses remain different every time.

And of them all, he definitely likes Tyler's the best.
