A new world didn't just arrive. It parked beside us.In Book 1: Lone Star, scout Wren and a semi-sentient ship found the impossible-an empty, beautiful planet with sleeping cities and a single survivor in the dark below. Kaelen woke to a foreign sun and a stranger's touch on a living console. Two lives bent toward each other. The door cracked open.Now, Book 2 begins.Earth names the planet Echo and rushes in-agencies, rivals, opportunists. Echo pushes back. The only way through its core systems is a console that demands a duet-two hands, matched pulses, shared intent. No solo access. No brute-forcing. Talk or turn back.Wren trusts machines more than people. Kaelen guards the sleepers and the bunker's sovereignty. Misreads come fast. Then small fixes start to land: a jammed door steadied, a power loop calmed, a first clean "sentence" in light and vibration. The circle of allies widens. So do the stakes.Partnership or possession. Accord or lockdown. Echo watches to see which story we choose.Double Earths is a tight, character-driven first-contact novel about consent, stewardship, and the hard work of learning to speak together before someone takes everything apart. It carries the mystery of Lone Star forward and points to a farther signal on the edge of the map.Perfect for readers who like smart sci-fi with atmosphere, quiet tension, and technology that talks back.Series orderBook 1: Lone StarBook 2: Double Earths (this book)Book 3: Three Homes (coming next)
