Rina Ralei Luzaria thought her world was complete - until the people she once called "friends" turned their backs on her without warning. Alone, hurt, and silenced by the weight of betrayal, she hides her pain behind laughter no one questions. No one knows what she's been through - not even her best friends since Grade 5, who remained unaware... until it was all over. But healing begins in the quiet. In the company of those who never judged her. With Sandra, Mark, Kyle, Zuphiro, Zehya - and her loving family - Rina slowly learns that losing people isn't the end of the world. Sometimes, it's the beginning of loving yourself.

"Sa Likod ng Katahimikan" Tahimik lang si Rina Ralei Luzaria. Hindi siya palakibo, hindi siya mapagpatol, at ang tanging hiling lang niya ay isang maayos at mapayapang buhay sa eskwelahan. Pero paano kung ang katahimikan mo ang batayan ng paninira sa'yo? Pitong estudyante. Pitong mukha ng kasinungalingan. Isang guro na paborito sila. At isang estudyanteng gusto lang sana ng kapayapaan-ngunit ginulo ng inggit, maling akala, at paninira. Kasama ang luhang tanging kausap tuwing gabi, matututunan ni Rina kung gaano kasakit ang pagtitiis at gaano kabigat ang mga salitang hindi niya kayang isigaw. Sa bawat chapter, ilalantad ang sakit ng katotohanan-at ang tahimik pero matapang na laban ng isang pusong sugatan. Hindi lahat ng tahimik, mahina. At hindi lahat ng ngiti, totoo.
