The Makabuhay Code

Some secrets don't stay buried. They grow.

When twelve-year-old Mariana "Mari" Reyes finds her late Lola's battered old book — The Medicinal Plants of the Philippine Archipelago — hidden inside a hollowed-out bamboo trunk, she thinks it's just a dusty botany textbook. But tucked between pressed leaves and faded Spanish handwriting is a secret code her grandmother left behind: a treasure map disguised as a plant guide, leading to the legendary Makabuhay Root — a plant so powerful, old island legends say it can heal any sickness and "give life back" to those who are dying.

Mari doesn't believe in legends. Not until her little brother Diego falls gravely ill and the local hospital runs out of answers.

With her fierce best friend Bea, a runaway carabao named Kalamansi, and a mysterious old herbolario (village healer) who may know more than he's letting on, Mari sets off on a race across the Philippine islands — from misty mountain forests to mangrove swamps, ancient banyan groves to smugglers' coves — decoding real medicinal plants, dodging a ruthless pharmaceutical scout who wants the Makabuhay Root for herself, and uncovering the truth about her grandmother's past.

Every chapter hides a real plant, a real clue, and a real piece of Filipino folklore — from the mustard family to the moonseed vine, from ginger to gumamela — turning an actual 19th-century scientific field guide into a thrilling jungle adventure, survival quest, family mystery, and ode to nature's hidden magic, all rolled into one unforgettable journey.

Perfect for young readers who love: botanical mysteries, treasure-hunt adventures, Filipino folklore and mythology, grandmother's secret journals, jungle survival stories, code-breaking puzzles, found family, sibling love, and stories where curiosity — and kindness — save the day.
