Null Pointer

The man in the cubicle beside him was dead. The police say it was a heart attack, but programmer Joshua Jones knows better. A message he found in the dead man’s code points to a psychotic hacker who can strike through the internet, leaving no trace. Relying on the advice from his tech savvy friends, Joshua must solve the mystery of who the killer is before becoming the killer’s next victim.


“Null Pointer is an excellent blending of computer technology, programmer knowledge and the traditional mystery.” – Angela Abderhalden, author of Questionable Ethics

“McConnell’s novel is filled with lots of technical details that geeks will love, but he makes nearly all of it clear to technophobes.” – Kathy McIntosh, Well Placed Words

Null Pointer is another tight, concise, attractive, appealing, and enjoyable read for me that new authors considering self-publishing should buy and use as a reference!  This is how it’s done!” – Shannon Yarbrough, The LL Book Review
