“Keys of Time,” examined from afar, is a fantastic work. The descriptive language, flowing words, and incredible prose set it slightly apart from the majority of debut sci-fi. Dialogue is well-written, not stilted or too forced, and throughout the entirety, it remains a time travel adventure that does not fall into the trap of confusion, with an interesting protagonist and enduring side characters. Time travel is a difficult concept to grasp, and an even harder one to write. The rules are undefined, just waiting to be formed, morphed into whatever the author feel is best for the continuation of the plot. Yohann Martin does a wonderful job at this in particular, however, the novel is a bit predictable, in the sense that the plot seems repeated from other media. The main obstacle in the way of five stars was this aforementioned repetitive nature— it is very, very, very difficult to write time travel stories without taking something that has already been done before— by no fault of the author, just simply because there have been so many in the past. Martin, with his beautiful, flowing language and enduring plot, would be better suited to carving out a space where millions upon millions of stories do not already reside. I can see him doing great things in the future, with newer ideas and concepts. Keys of Time is a good novel— but when competing against the many other tales of time travel adventures, it fails to stand out. This isn’t to say that it wasn’t an enjoyable read, not at all, but rather to imply that if shelved with alike books, it would not catch my eye. The switch between dialogue and thought can be abrupt at times, but nothing off-putting, and otherwise Martin does a neat job of wording his character’s emotions. Overall, “Keys of Time” is a page-turner-- if you pick this novel up, clear your schedule for the next few hours. Yohann Martin holds great potential. I, for one, will be looking forward to seeing what masterpieces he is able to create in the future.
