The Breakthrough series launched with its namesake novel in 2013 and has grown into a seven-book saga. The story begins with researchers studying dolphin communication and quickly expands into territory involving ancient artifacts, advanced technology, and questions about humanity’s place in a much stranger world than anyone expected. Genesis, Leap, and Catalyst built the foundation, while later entries like Ripple, Mosaic, and Echo widened the story further.
Grumley writes with enough scientific grounding to make the ideas feel plausible while keeping the thriller pacing that moves readers through each book quickly. The series rewards readers who start from the beginning, as plot threads accumulate and pay off across multiple volumes.
