Storm Season is one of the series of successful novels featuring Derrick Storm written by Richard Castle in the years before he met Beckett at the start of the series. Although the text novel is referenced in the show, unlike some other Storm books, it has never existed in the real world. However, it is one of the four Storm novels that have been published by Marvel as a graphic novel in the real world. It is the only one of Castle's books that has appeared on screen in two different formats.
(From richardcastle.net; the Marvel graphic novel summary on Amazon is the same): Derrick Storm is hired to bug the hotel suite of an African head of state - but what should have been a routine mission quickly spirals out of control when Storm overhears a woman's terrifying scream on the wire. Plagued by the victim's helpless cry, Storm - despite an ominous warning - investigates. Soon, he'll discover an international conspiracy reaching further than he ever imagined - and perhaps the truth about Clara Strike, a CIA agent the world thinks is dead!
