In this instant bestselling novel from author Daniel Kalla, a Vancouver doctor and a detective face the deadly consequences of the opioid crisis as they track down the supplier of fentanyl that landed a group of teens in the ER with critical overdoses.

Deliberately or not, they must’ve been poisoned…And if it happened to them…
There will be others.

Dr. Julie Rees, a toxicologist and ER doctor, is stunned when her emergency room is flooded with teenagers from the same party, all on the verge of death. Julie knows the world of opioids inside and out, and she recognizes that there’s nothing typical about these cases. She suspects the teens took—or were given—fentanyl. But why did they succumb so quickly?

Detective Anson Chen is determined to find out. He and Julie race to track down the supplier of the deadly drugs. But the trail of suspects leads everywhere, from unscrupulous street dealers to ruthless gang leaders who hide behind legitimate business fronts and the walls of their mansions.

As Anson and Julie follow clues through the drug underworld, Julie finds herself haunted by memories of her troubled past—and the lover she lost to addiction. When other overdoses fill the ER—and the morgue—Julie realizes that something even more sinister than the ongoing fentanyl crisis is devastating the streets. And the body count is rapidly rising.

A gripping thriller, The Last High explores the perfect storm of greed, addiction, and crime behind the malignant spread of fentanyl, a deadly drug that is killing people faster than any known epidemic.
