My husband has read everyone of the swagger books and passed them on to me as I love action films and novels. You don't particularly have to know a lot about guns, bullet sizes etc to just enjoy how this story unfolds. Hunter gives you a real sense of history and the attention to detail really draws you in, the characters are intriguing and believable.
It's best to read the previous books by him as Black Light will then gel Bob and Earl's story together and make more sense. So you don't have to be a bloke to enjoy Hunters books ! stick with it and you really won't be able to put it down once you start reading !!
