A tragic accident. A family in crisis. And a killer watching every move. Five months after the mysterious death of his wife, Stephen Porter is pulled from a dreamless sleep by a midnight phone call. His 17-year-old daughter Sara is stranded in a blizzard near the top of a mountain beyond their suburban home. She's terrified and unable to stop crying as she begs him to come to her rescue. Unfortunately Stephen went to bed just an hour before after a night of binge drinking. With his blurred vision and unsteady balance he knows it’s dangerously irresponsible to get behind the wheel. But he heads out into the snowstorm to bring Sara home. High school teacher Kieran O’Shea is also behind the wheel, searching for his autistic younger brother Aidan, who is wandering aimlessly through the storm on that same mountain. Kieran is terrified—of the voices in his mind, that Aidan will be taken from him, and that he may soon be arrested for murdering three women. In a matter of minutes Stephen will encounter Kieran and drive headlong into a collision that will force him to unlock the secret of his wife’s death, avoid prosecution, and protect his children from violence that hits all too close to home.

Harness the power of real options Real options theory is based on the Nobel Prize--winning work on financial options, and has captured the interest of executives, managers, and investors who need to understand the future profitability of an asset. Originally developed to value technology initiatives and companies, the method is now being applied broadly across various businesses and industries. The Real Options Solution offers comprehensive coverage of the real options approach with a five-step framework and examples for applying the author's unique total value model based on real options analysis. This approach will help executives and investors minimize the risk of committing to new ventures and delivers a framework flexible enough to apply to business initiatives in all types of companies.

Hacking is the art of creative problem solving, whether that means finding an unconventional solution to a difficult problem or exploiting holes in sloppy programming. Many people call themselves hackers, but few have the strong technical foundation needed to really push the envelope. Rather than merely showing how to run existing exploits, author Jon Erickson explains how arcane hacking techniques actually work. To share the art and science of hacking in a way that is accessible to everyone, Hacking: The Art of Exploitation, 2nd Edition introduces the fundamentals of C programming from a hacker's perspective. The included LiveCD provides a complete Linux programming and debugging environment—all without modifying your current operating system. Use it to follow along with the book's examples as you fill gaps in your knowledge and explore hacking techniques on your own. Get your hands dirty debugging code, overflowing buffers, hijacking network communications, bypassing protections, exploiting cryptographic weaknesses, and perhaps even inventing new exploits. This book will teach you how to: – Program computers using C, assembly language, and shell scripts – Corrupt system memory to run arbitrary code using buffer overflows and format strings – Inspect processor registers and system memory with a debugger to gain a real understanding of what is happening – Outsmart common security measures like nonexecutable stacks and intrusion detection systems – Gain access to a remote server using port-binding or connect-back shellcode, and alter a server's logging behavior to hide your presence – Redirect network traffic, conceal open ports, and hijack TCP connections – Crack encrypted wireless traffic using the FMS attack, and speed up brute-force attacks using a password probability matrix Hackers are always pushing the boundaries, investigating the unknown, and evolving their art. Even if you don't already know how to program, Hacking: The Art of Exploitation, 2nd Edition will give you a complete picture of programming, machine architecture, network communications, and existing hacking techniques. Combine this knowledge with the included Linux environment, and all you need is your own creativity.
