This story is massive in its scope and one thing I appreciated from the author, especially given that this is the first book in a series, was the time she spent to introduce and understand the principal characters in this strange new world. Too often fantasy authors leave us, the reader, to flounder along wondering who is this character and why is he/she reacting this way. Davidson takes the time to build her world, to set the scene and to explore her characters. I applaud her for this.
Once the adventure starts, the action is fascinating and beautifully written. We are able to follow the various arcs of the story and relate one to the other, which is the sign of a superb writer, which Davidson certainly is. I particularly liked the emotional nature of the interactions between both the humans and the humans to the immortals. There was always a deep feeling of mistrust and fascination between the two groups, which was wonderfully played by Davidson. The principal character (if there can even be one in such an ensemble cast) Rayne of the Mantle was perfectly complex and riddled with issues, especially identity issues. I look forward to exploring more of these fascinating characters in the next few books in this series.
Davidson is both prolific and talented as an author and I would certainly place her high up in the list of indie authors I have read and as a fantasy author, she is up there with the very best. An author to follow for sure. I highly recommend The Infinity Mantle, if fantasy is your genre - and even if it's not, I suggest you give this one a crack.
