What the readers are saying about GENESIS
★★★★ “This book is a very interesting continuation to the series. The story continues in the near future and involves a few of the same story lines as well as a few additional ones. The different stories come together towards the end. I was surprised by a few of the things that happen in this book. I thought the book was well done. I recommend this book if you are into science fiction and like it in the near future. My only issue was that at times the sentences don’t quite make sense to me until I flip a word or two around in the sentence. This caused a few stops for me until I reread the sentence to figure it out.” – AMAZON REVIEW

What the readers are saying about TRIDENT
★★★★★ “This final book in this trilogy, is amazing. The 1st 2 books had a good story, but this capped them all, the pace was fast,it was had to put down,” one more page”,but 1 page turned into many. The end was literally explosive! It makes way for possible future books, I hope so. The author, Filip, is a talented writer,and as I said earlier, a modern day Jules Verne. The whole book is so well written, one can identify with today’s environmental problems,but I hope the end is different!” – GOODREADS REVIEW
