Ambition at Heart: A Cardiopharmacology Thriller

By Judah Oyin

Lydia Helen runs Voss Meridian Group from the fourteenth floor of a Lagos tower, manages a 287,000-strong LinkedIn following, and operates on four hours of sleep across three time zones without visible strain. She has built an infrastructure company from a desk in Yaba into one of the most respected logistics firms in West Africa, and she has done it on adrenaline, in the precise pharmacological sense: epinephrine binding to beta-adrenergic receptors in her heart, driving rate and output and the sustained performance that eleven years of relentless work demands.
Then a nurse on a red-eye from Dubai puts two fingers on her wrist.
The diagnosis is atrial flutter and hypertensive remodelling. The drug is propranolol. And what follows is a story about what happens when the molecule that has been powering your ambition is the same molecule your cardiologist needs to block.
Ambition at Heart is a cardiovascular pharmacology thriller set across Lagos, Dubai, Singapore, and London, following Lydia through her first propranolol prescription, a critical government infrastructure bid, a covert switch to bisoprolol, and a corporate threat she must outmanoeuvre using the very pharmacological knowledge she has spent a year acquiring. With clinical precision and narrative urgency, the novel explores beta-adrenergic receptor blockade, first-pass metabolism, CYP2D6 intermediate metaboliser status, drug-drug interactions, and the structural remodelling of a heart that has been working too hard for too long.
For readers who want their pharmacology without compromise, their fiction without condescension, and their thrillers built from something that could genuinely happen to a person sitting in a business-class seat somewhere over the Arabian Sea right now.
