The Graviton Wars Books in Order

The Graviton Wars is the later presentation of Falconer's Lucas Ramsay saga, packaged around the Gravity Wave books. If Narrows Of Time is the original version, this is the cleaner big-series face of the same idea: one experiment goes wrong, the universe notices, and Earth pays for it.

Lucas Ramsay begins as a scientist convinced his reactor can change everything for the better. In a way, it does. The problem is that the device does not just open a path toward exploration. It sends a violent signal into territory that belongs to powerful alien forces. From there the series grows fast. Earth becomes a target. Advanced species descend on the planet. Humanity scrambles to survive while the people closest to the disaster try to work out whether any part of it can still be undone.

The trilogy mixes several kinds of science fiction at once. There is alien invasion spectacle. There is survival fiction as civilization buckles. There is time-travel problem solving through the incursion chamber. And there is multiverse trouble once Lucas begins pulling too hard on the timeline. By the third book, the fight is no longer just against outside enemies. It is also against paradox, alternate selves, and the idea that every fix may create another fracture.

That sounds huge, and it is, but the books work best when they stay close to Lucas and his determination to repair what his work set loose. He is not written as a flawless genius. He is a man trying to outthink consequences that have already outrun him. That gives the series a useful human center even when the action turns cosmic.

The tone is pulpy in the good sense, fast, dangerous, and willing to swing for big ideas.

If you want Falconer in full sci-fi mode, start here with Gravity Wave. Readers who like alien empires, collapsing worlds, and time-travel attempts to pull victory out of disaster will find a lot to enjoy. If you notice echoes of Linkage, Incursion, and Reversion, that is because this series grows directly out of that earlier Lucas Ramsay trilogy.
