Summary 
From the book jacket
He is perhaps the ultimate Human achievement: a sentient life-form; self-aware, self-determining, possessing a mind and body far surpassing that of his makers, and imbued with the potential to evolve beyond the scope of his programming. Created by one of the most brilliant and eccentric intellects the Federation has ever known, the android Data has always believed he was unique, the one true fulfillment of a dream to create children of the mind.

But is he?

Investigating the mysterious destruction of a new android created by Starfleet, Data and the crew of the  uncover startling secrets stretching back to the galaxy's dim past. That knowledge is coveted by beings who will stop at nothing to control it, and will force Data to redefine himself as he learns the hidden history of artificial intelligence.

Background information 
 Although the Pocket DS9 novel Abyss is Lang's first published Star Trek novel, he began work on Immortal Coil first. He considered it "a bear of a story", noting that it was also his first experience of writing prose fiction. ()
 It was Pocket editor Marco Palmieri, who Lang had approached about writing Star Trek fiction having worked with him previously at DC Comics, who devised the idea of exploring Noonien Soong's development of Data. This eventually led to a wide-ranging exploration of artificial intelligence in the Star Trek universe. As Palmieri observed "One of the things that’s always troubled me while watching Star Trek is how casually sentience is created […] and how often it went wrong. With the possible exception of , it seemed as if the power to create a mind was pretty much taken for granted. I thought someone needed to step up and point out what was wrong with that – be a voice for AI. From that we came up with the idea of the character of Emil Vaslovik, who has very well-established, personal reasons for taking up that cause." ()
 Many of the characters and concepts featured in this novel would later be explored in the Cold Equations trilogy, and in Lang's own follow-up to that, The Light Fantastic.
 The title  references a quote from Hamlet by  William Shakespeare: "...what dreams may come / When we have shuffled off this mortal coil..."
