Free on Kindle!

I enjoyed this one and gave it a four-star rating. 
From Smith Publicity:
From today through Monday, debut ‘smart’ sci-fi thriller Casimir Bridge, is available for FREE on Kindle. Enjoy the long weekend with tantalizing futuristic technology, deep space adventure, and thrilling plot twists. Casimir Bridge is a nuanced, thought-provoking, and deeply human space opera that draws the reader in and never lets go. Debut author and former NASA Space Shuttle engineer Darren Beyer puts the science back in science fiction with his deep knowledge of space travel and flight to give realism and depth to a genre that all-too-often leans on quixotic and half-baked tropes. 
"Nefarious bigwigs, collusion and galactic jumps against a cosmic backdrop; readers should definitely want to come back for more.” - Kirkus Reviews
