JUSTINE KNOWS SHE’S GOING TO DIE. ANY SECOND NOW. Justine Jones has a secret. A hardcore hypochondriac, she’s convinced a blood vessel is about to burst in her brain. Then, out of the blue, a startlingly handsome man named Packard peers into Justine’s soul and invites her to join his private crime-fighting team. It’s a once-in-a-lifetime deal. With a little of Packard’s hands-on training, Justine can weaponize her neurosis, turning it outward on Midcity’s worst criminals, and finally get the freedom from fear she’s always craved. End of problem. Or is it? In Midcity, a dashing police chief is fighting a unique breed of outlaw with more than human powers. And while Justine’s first missions, including one against a nymphomaniac husband-killer, are thrilling successes, there is more to Packard than meets the eye. Soon, while battling her attraction to two very different men, Justine is plunging deeper into a world of wizardry, eroticism, and cosmic secrets. With Packard’s help, Justine has freed herself from her madness—only to discover a reality more frightening than anyone’s worst fears. From the Paperback edition.

The Rust programming language is consistent and does its best to avoid surprising the programmer. Like all languages, though, Rust still has its quirks. But these quirks present a teaching opportunity. In this book, you'll work through a series of brain teasers that will challenge your understanding of Rust. By understanding the gaps in your knowledge, you can become better at what you do and avoid mistakes. Many of the teasers in this book come from the author's own experience creating software. Others derive from commonly asked questions in the Rust community. Regardless of their origin, these brain teasers are fun, and let's face it: who doesn't love a good puzzle, right? What better way to exercise your brain and increase your Rust programming knowledge than with a collection of dynamic brain teasers? As you read through each of these puzzles and try to work out the answers, you'll not only learn about Rust's unique quirks and peculiarities, you'll also have loads of fun along the way. Dive right in and get started with example code and sample problems that cover numbers and text, shadowing and memory, and everything in between. Try to figure out why a particular program won't compile, why it produces unexpected output, or why it panics and terminates with an error message. Once you've run the code and read the answer, it's time to get to the heart of the matter with a detailed explanation. Learn why a program produced the result it did, and discover how similar issues might affect the code you write in your own programs, even in production. Sourced from engaging discussions within the Rust community, real-world problems, and even reader feedback, these challenges will certainly surprise, enlighten, and entertain you. Are you ready to experience Rust like never before? Then sharpen your brain and get ready for a challenge! What You Need: This book assumes you have some knowledge of the Rust programming language. To work through the brain teasers in this book, you'll need a working Rust environment on any platform. You can install Rust by visiting https://rustup.rs/. You'll also need a text editor or Rust-friendly IDE.
