In time order, it would be 3.5, but you can read it alone, because it is about side characters.

THERE'S A THIN LINE BETWEEN LOVE AND DOOM.

No wager is too outrageous for Simon Fitzgerald, the most reckless of the Disillusionists. His dark secrets drive him to take increasingly extreme risks, but he's never lived so quite so dangerously as when he hooks up with Midcity's most powerful prognosticator.

Fawna Brady is tormented by the destinies she sees for those around her. To Fawna, knowledge of the future is a cage she'd do anything to escape. She's stunned to discover a taste of the freedom for which she yearns at the side of Simon, the one person in the world who despises everything she is, everything she stands for.

Simon's defiant attitude toward destiny captivates Fawna, but will her love destroy him? And will Simon rush headlong into the delicious doom she offers?
