YA Guy Reveals... The Cover to the Final Book in the Ecosystem Cycle!

YA Guy's initial conception for the Ecosystem series was to wrap it up in three books. But Book 3 didn't quite conclude the series to my satisfaction, so I decided to add a fourth and final installment (thus transforming the series into a "cycle" instead of a mere "trilogy"). Titled The Last Sensor, it's due to come out early next year (by my birthday, February 5, if I can swing it).

Today, though, I'm ready to reveal the cover, which is (if possible) my favorite in the entire series.

Pretty cool, huh? Here's the blurb:

Fifteen years ago, war nearly destroyed the City of the Queens. In the time since, Queen Rebecca’s reign has been marked by reconciliation between the Ecosystem and its people. With the aid of Chief Sensor Miriam and her husband Isaac, an era of peace and prosperity seems to have been assured at last.

But then a new and unparalleled threat arises: the Ecosystem itself is dying, and Rebecca is powerless to restore it. Joining the Queen’s guard in their search for a cure to this mysterious malady is teenage apprentice Hadassah, daughter of Miriam and Isaac. For her, the quest is deeply personal: she seeks word of her friend and guardian Sarah, the former queen of the city who has been missing for years. Hadassah’s journey will take her to the ends of the earth, to a place of legendary wonder, beauty, and danger. And it will require her to tap a source of power even the queens have never imagined if she is to save her family and heal her world.

So enjoy the cover, and let me know what you think! I'm really excited to bring this series to a close; it's been near and dear to my heart for many years, and I hope readers will be as pleased as I am with the places the final book takes them!
