The galaxy is on fire. The ruthless Adamant Empire is sweeping across all of space leaving only chard ashes in their wake. No civilization can withstand their firestorm of conquest. But they made one serious mistake along their path to galactic domination. They pissed off Jon Ryan. Bad move. That's never a healthy thing to do.
Now in their darkest hour, the few remaining islands of freedom and light left untouched band together in a last-stand effort to stop the evil juggernaut. But will their best efforts and Jon's uncanny knack to pull off miracles be enough? And will the magical race of dragons join the fray and possibly turn the tide of war? If they remain aloof and uninvolved, it's likely the final surviving planets will surely fall.
Dragon Fire is Book 5 in the fast paced, funny, and fresh Galaxy On Fire Series.

270 pages, Kindle Edition

The Seven Lives of Craig A. Robertson

Dr. Craig A. Robertson is a physician and the author of more than forty-five published science fiction novels. Getting there, however, was anything but a typical path.

His first life was that of a shoe salesman. This "profession" helped him to work his way through college. His first experience was at Kinney Shoes. leveling up to Sears, and eventually became a shoe manager at Montgomery Ward. All three companies later went bankrupt. Not. His. Fault. But he did meet his wife, Karen, at Sears, which made working there most rewarding.

His second life embraced the physical sciences. A childhood fascination with astronomy led him to UC Berkeley. However, he eventually switched to geophysics after realizing that astronomers spent an inordinate amount of time alone on cold, remote mountaintops. Somewhere along the way, physical science gave way to his true passion: medicine.

For his third life he
became a doctor. Medical school and residency were like being sentenced to an abusive gulag, but they provided two lasting benefits. First, he learned that nothing he encountered afterward would ever be harder. Second—and rather more importantly—he got to be a doctor.

His career began in academic medicine, when he became a professor of Emergency Medicine at a Level One Trauma Center. That was followed by yet another incarnation, this time as a research immunologist at UC Davis, where his work included a cloned antibody directed against human melanoma cells and research into primary biliary cirrhosis.

Eventually, Craig settled into the life of a practicing physician. But somewhere among patients, science, family, and all those previous incarnations, another life crept onto the scene.
He became a science fiction writer.

More than forty-five novels later, Craig spends a psychiatrically questionable amount of time destroying planets, rebuilding civilizations, tormenting his delicious evil villains, and making Jon Ryan traverse the universe ... forever.

It seems doubtful, given his past inclinations, that seven lives will be enough for Craig A. Robertson.

This is a review for the Galaxy on Fire series as a whole. The first two are included in Audible Plus, and I highly recommend them. Scott Aleijo does a great job with the narration with hilarious voices. The entire series is included with Kindle Unlimited so I read the rest of the series on my Kindle. I have to say I was imagining the voices as interpreted by Scott.
Overall it’s a fun, easy to read series. No hard science here, just action and snark. I like the deep time aspect even if it doesn’t really make sense his android body is still functional. These novels are not very long and can easily be completed in a day or two. Luckily there’s over twenty novels in the Ryanverse to keep you busy.
