The dead won't stay dead. The living may never be safe.

John Thompson's life as sidekick to psychic Jacob Daniels just got complicated. Strangers are delivering urgent messages they don't remember giving. A telepath with shattered mental barriers is hearing voices from across the city. Something that feeds on psychic energy is getting stronger.

What starts as helping one person spirals into encounters with abilities John never knew existed and threats that turn ordinary people into unknowing pawns. Each supernatural incident reveals new layers of a mystery that stretches back generations.

When ancient forces begin moving through modern lives, John must choose between the safety of observation and the danger of action. Because the network of psychic phenomena he's spent years trying to understand isn't just real—it's under attack.

And the enemy has been searching for a weak link.

Some doors should never be opened. Others open themselves. Will John be ready when something steps through?

The forces are gathering. The doors are opening. And John Thompson's investigation is about to become a fight for survival. Read SUMMONS AND VISITATION now—before the dead decide you belong to them too.

John Thompson talks to the dead. They keep talking back.

He lost his sister to a killer and his parents to grief so complete it killed them. What remained, John poured into a paranormal research facility, a quiet mission, and a team of gifted people who refuse to let the past stay buried.

When a gun with a dark history finds its way to them, the psychics discover it carries more than ballistic evidence. Every hand that touched it left a mark, and every mark deserves an ending.

Across the city, a ghost moves through strangers' houses with a single purpose, searching for the one person alive who can see her clearly enough to act.

John's gift may be the only thing standing between a killer who slept soundly for decades and the justice he never saw coming.

Can the dead finally rest, or has too much time passed for the truth to matter? Dive in and find out.
