So far I've read...
Marla Miniano: Every Girl's Guide to Flings and Table for Two
Melissa Dela Cruz: Blue Bloods and Masquerade
Vince O. Teves: Getting Over Andrea and The Wedding
Miguel Syjuco: Ilustrado
Andrea Pasion: Have Baby, Will Date
Maya O. Calica: Undercover Tai Tai
Claire Betita: No Boyfriend Since Birth
The cool thing is that not all of them are locally published, and not all are necessarily "Pinoy" in subject matter either.
