Comienza 2 años después del anterior libro y es, una vez más, un libro puente para esbozar los nuevos malos que vendrán después. Muy entretenido y palomitero en la línea de la saga.

PEEEEEERO PEEEEEERO PEEEEEERO, me he enterado de una cosa que me ha hecho levantar, no una, sino las DOS cejas muy alto y muy fuerte:
El colega (vamos a llamarlo así) publicó en 2025, 53 libros. Sí, ¡53! y en en 2026 aproximadamente...¡60! Ni el rey la paja Brandon Sanderson escribe a ese ritmo. Aquí huele a puta IA, o bien a granja de escritores que estén enjaulados y sean alimentados mediante tubos mientras les dan latigazos para que escriban más rápido.
Me acaba de dar mucho repelús, y mira que estoy disfrutando estos libros pero me fastidia...mucho mucho.... :_(

More of a “kids of Agent Zero” book. Earlier books are more focused on the MC.

Never stops!

No better plotmeister exists!! Mars keeps the incredible twists and turns coming. By book 13 you will part of Zero’s family without a doubt! A little better proofing would be only comment! Pronouns often mixed like her when he means him. Some portions of whole chapters he uses the wrong name for the character like Mariah when he meant Maya or Alan when he means Zero etc etc. usually corrects after several chapters but all things a computer copy editor would miss.

Read the whole book in one sitting!

Love Jack Mars’ writing skills and all of his books! This one was no exception. Be prepared to not be able to put it down once you start reading it.

This story was filled with nonstop action and overlapping memory updates from the past stories. It was a wonderful and enjoyable reading for me. What a story.
