Is she real or Memorex?

T. S. Falk keeps upping his thriller game. With Exogenesis, he has written a tightly-crafted, atmospheric and suspense-driven speculative fiction novel that will leave you yearning for the next one.

Falk's command of prose creates characters you won't forget, far-flung environments that appear whole before your eyes, and detailed scenarios tense enough to build your blood pressure to dangerous levels.

Exogenesis is a powerhouse of a thriller, something especially great for a second book in a series. I, for one, cannot wait for the next book to be released. Excellent work by T.S. Falk, well deserving of a 5-star rating.

'The Source' Is Back...

Exogenesis is a sci-fi thriller revolving around an organism capable of rapidly causing rapid evolution via an epigenetic cascade in organisms exposed to it in utero. The pace is fast, the writing as good as I have come to expect from anything Falk writes, and there is just enough science to satisfy a geek like me! This is a great follow-up with an ending that will keep you guessing and sets up another book. It can't come soon enough! Overall, 5/5 stars, highly recommended for any reader looking for some science with their thriller!

a fantastic read, tense and dramatic

A gripping tale, filled with lots of personal detail, great scene descriptions, and somewhat over-the-top genetic jargon, the writing is well done, though this particular book could use a little more thorough editing.
The subject matter, exogenesis, if it were real and took the form as described in this story, would be totally terrifying. It could mean the end of life as we know it on Earth.
The plot had a number of twists, and at times it seems the story could have gone in other directions, which kept me guessing and interested to see what happens next. A little twist near the end hints at another book in the series. Can’t wait.

nog beter, spannender en gelaagder dan de eerste

Ik hoop dat er nog meer delen komen, want deze verhaallijn verdient het om verder te gaan. Je kan er alle kanten mee op. Super verhaallijn

Exogenesis

This book is packed full of a lot of action, and more. The more part is some interesting ideas about evolution, or what causes it. You might not believe the implications.

Non Stop!

Absolutely non stop action and adventure. A stand alone sequel with mostly new characters. Thrilling and difficult to put down.
