Clarinet Reid is a typical teenager on the surface, except she has a centuries-old Druid blood curse running through her veins. She is locked in a deadly race to find a stolen artifact, avert an explosive catastrophe, save a Celtic warrior princess, and right a wrong that happened centuries before.

A lo largos de algo más de dos años, tomando fotos y entrevistando,, se recolectó este texto para mostrar aquello que se nos pasa por alto, pero que forma parte de nuestra cultura. En Usaquén se reunen todos los requisitos para constatar que es necesario detenernos para mirar hacia sí, y observar aquellas cosas que no vamos a ver en la televisión, ni hallar en las noticias de un periódico, pero que son parte sustancial de nuestra manera de ser. Siempre se tuvo la sensación de que los bogotanos y los extranjeros pasan por Usaquén en carro y no a pié, y sólo se llevan una efímera impresión que dura unos instantes, y se olvida luego del trancón o la dificultad para parquear. Se pierde así el sentimiento que deja en el alma encontrarse con lo propio, es decir, aquello que nos distingue del resto del mundo.

"It is summer and the Canadian Rockies are on fire. As the forests blaze, Alan West heads into their shadows, returning from university to his grandfather's home in the remote Kootenay Valley, wherethe man who raised him has suffered a heart attack. Confronting his own mortality, the tough and taciturn Cecil West has a dying request for his grandson: track down the father Alan has never known so that the old man can make peace with him. And so Alan begins his search for the elusive Jack West, a man who skipped town before his son could walk and of whom his grandfather has always refused to speak. His quest will lead him to Archer, an old American soldier who decades ago went AWOL across the border into Canada. Archer has been carrying a heavy burden for many years, and through him Alan learns the stories of two broken families who came together, got too close, and then fell apart in tragic ways.Ballistics is a remarkable first novel, about family ties and the wounds that can linger for generations when those relationships are betrayed"--
