Lexi Revellian has many skills as a writer but she has one in particular that appeals to her readers - she creates believable, interesting characters. She also avoids clichéd and stereotypical ones which, to me, is equally important.
The lead character in 'Replica', Beth, (actually there are two of her, hence the title) is seemingly innocent and attractively vulnerable yet, at the same time, we learn, she is a woman who is intelligent, determined and resourceful. In both forms, this character had me feeling an affinity for her and, as a man, wanting to do something to help and protect her. That's a remarkable feat for an author to achieve and is the reason I've given this book my first 5 star rating.
I know well someone who is employed in the British security services, and the way the author deals with this aspect of the plot would indicate that she has carried out some research on the matter (something I've found that few other new authors here on Kindle Books hardly ever bother to do). So, full marks for that too. EDITED to say that I failed to notice the slip-up relating to Beth's entry to Thames House (and which the author reports in her comment to CEEAITCHJAY that she has now corrected) - I was reading in bed and must have been dozing off at that point!
Having said that, the basic premise of the plot requires an extremely elastic imagination. However, once you've got your imagination at full stretch and accepted that premise, the book takes off and is a veritable page turner.
My only criticism (and this also applied to the author's first book, 'Remix') is that the ending was, for me, a little too short and sudden.
From a technical standpoint, the attention to formatting, spelling and grammar, and also geographical accuracy, is impeccable, with the result that the book exudes professionalism.
As I said in my title for this review... Highly Recommended!
