This is again the great Giebel, the author excels at each of his books.
"Just a Shadow" is a highly psychological thriller. The characters are simply peeled, pace, plot well constructed and perfect writing. For every pound of Karine Giebel, and this one is no exception to the rule, the reader is simply a privileged witness: he lives to the rhythm of the characters sharing their doubts, fears, questions, fear, fight.
No unnecessary line, no filler.
It's pure happiness and all those who regularly write they could not "release the book", this phrase takes on its full meaning.
Congratulations to the author.
