Author Travis Luedke's Angel 6.0 series is the best erotic, thriller, adventure, way out there, sci-fi series ever. I'm elated that he has put them in to one box set, now I can sit and read from beginning to end and moan, groan, yell, jump, get mad and let out a what the f--- now and then, all at one long sitting, (well maybe a few more). If your a fan of strong women characters, blood and guts, sex that'll blow your mind, and all happening in the sci-fi world, you must not past this series up. You will love every step Angel 6.0 makes from beginning to end and will yell for more when it's over. .
