“Original review: 07 November 2025Rating: 3.75 starsThis was a solid book overall, but sci-fi isn't exactly my favourite or preferred genre to read, however, there were quite a few things about this book that I loved. One of them in particular is the main character…”
“I loved this book... which leads to believe that the sun and the star was such a train wreck because Rick let another author have control, this was stunningly written, the plot was moving fairly quickly, the characters were all given their moment in the spotlight... 10/10”
