From the pdf book "The Fault in Our Stars" by John Green. Actually before, I have no intention of reading it because almost everyone around me reads it but I'm like, "I don't need to read it." But then nung vacation, parang I wanted to read it kasi ang daming taong gustong maread yun. So I looked for pdf version. Then there! I'm reading it na! I'm glad naman. It teaches a lot of moral lessons and also about science. Haha.
