In this explosive new thriller from international bestselling author Daniel Kalla, an experimental vaccine is deployed to battle a lethal outbreak—until patients start dying of unknown causes.

An ordinary day
The city of Seattle is stunned when a deadly bacteria tears through a nearby Bible camp. Early tests reveal the illness is a form of meningitis, and the camp’s residents are among its most vulnerable victims: children and teenagers.

A new vaccine
Facing a rapidly rising death rate, Seattle’s chief public health officer, Lisa Dyer, and her team quickly take all steps necessary to contain the devastating outbreak. And when further testing reveals that the strain of the bacteria is one that caused catastrophic losses in Iceland six months before, Lisa decides to take a drastic step: she contacts Nathan Hull, vice president of a pharmaceutical company that is doing final-phase trials on a viable vaccine, and asks him to release it early for use on the city’s population.

An epidemic in the making
Lisa gets the go-ahead on her controversial plan, despite the protests of dubious government officials, anti-vaxxers, and even those on her own team. Vaccine clinics roll out across the city, and the risky strategy appears to be working, leaving Lisa, Nathan, and thousands of others breathing a sigh of relief. Until people start dying from mysterious and horrific causes—and the vaccine itself is implicated.

But what if science isn’t to blame?

Praise for The Last High

“Kalla has long had his stethoscope on the heartbeat of his times. . . . In his latest, the focus is on Vancouver’s opioid crisis. . . . [A] lively story.”
— Toronto Star

“A thrilling, front-line drama about the opioid crisis.”
— KATHY REICHS, bestselling author of the Bones series

“If you want an engrossing, edge-of-your-seat thriller that combines good detective work, corruption, savage criminal practices, a dark, seamy portrait of a large Canadian city, and a hard-hitting lesson on the medical and emotional effects of opioid drugs, then The Last High certainly fills that prescription.”
— Montreal Times

“Kalla is terrific at building suspense as the case progresses, uncovering a web of dealers, sellers, and users.”
— The Globe and Mail

A riveting thriller, The Last High features the most evil and insidious of villains: opioids. This important, must-read book is not only well-researched and entirely realistic, it gives a human face to a devastating epidemic.”
— ROBYN HARDING, #1 bestselling author of The Swap

An exciting police/medical thriller that’s an even better sociological alarm bell . . . everything feels real.”
— Winnipeg Free Press

“A sobering glimpse into the drug overdose crisis. . . . An entertaining, if slightly eerie read.”
— Vancouver Sun

Praise for We All Fall Down

A tightly plotted thriller, energetic and completely believable. Kalla knows how to build a suspenseful story that doesn’t stretch the bounds of plausibility. He also knows how to build realistic characters and put natural-sounding dialogue into their mouths, something many better-known medical-thriller authors often struggle to do. . . . [a] top-drawer thriller.”
Booklist

A fast-paced thriller with an historical overlay and a dash of romantic tension.”
 Vancouver Sun

Kalla inherits the mantle of Michael Crichton. . . . Much more than a medical thriller, We All Fall Down is both a vivid history lesson and a heart-pounding warning, resulting in a page-turning obsession.”
— STEVEN HARTOV, New York Times bestselling author of The Soul of a Thief
