Adrenaline is the first novel written by James Robert Baker (1946–1997), an American author of sharply satirical, predominantly gay-themed transgressional fiction.

A native Californian, his work is set almost entirely in Southern California, and the book is about two "lusty" gay lovers from Los Angeles named Nick and Jeff who at the beginning of the novel were having passionate sex when two "wildly homophobic cops" break in on them.

[16] Planet Out noted the book as an "unapologetic jackhammer of anti-right, anti-homophobe, anti-corporate invective, despised by polite gays, embraced by activist queers, and garnered both hostile reviews and exuberant word-of-mouth.

[18][19] Though he garnered some fame for his books Fuel-Injected Dreams and Boy Wonder, according to his life partner the move to more mainstream novels instead of writing the fiction he wanted to create were a contributing factor in his suicide.

[1][20] As of 2006[update], first editions of Adrenaline, Boy Wonder, Fuel-Injected Dreams, and Tim and Pete have become collector's items and command high prices at rare book stores.
