Dean Koontz has surpassed his longtime reputation as America’s most popular suspense
novelist (Rolling Stone) to become one of the most celebrated and successful writers
of our time. Reviewers hail his boundless originality, his art, his unparalleled
ability to create highly textured, riveting drama, at once viscerally familiar and
utterly unique.

Author of one #1 New York Times bestseller after another, Koontz
is at the pinnacle of his powers, spinning mysteries and miracles, enthralling tales
that speak directly to today’s readers, balm for the heart and fire for the mind.
In this stunning new novel, he delivers a tour de force of dark suspense and brilliant
revelation that has all the Koontz trademarks: adventure, chills, riddles, humor,
heartbreak, an unforgettable cast of characters, and a climax that will leave you
clamoring for more.

Dylan O'Connor is a gifted young artist just trying to do the
right thing in life. He’s on his way to an arts festival in Santa Fe when he stops
to get a room for himself and his twenty-year-old autistic brother, Shep. But in
a nightmarish instant, Dylan is attacked by a mysterious doctor, injected with
a strange substance, and told that he is now a carrier of something that will either
kill him…or transform his life in the most remarkable way. Then he is told that
he must flee–before the doctor’s enemies hunt him down for the secret circulating
through his body. No one can help him, the doctor says, not even the police.

Stunned,
disbelieving, Dylan is turned loose to run for his life…and straight into an adventure
that will turn the next twenty-four hours into an odyssey of terror, mystery–and
wondrous discovery. It is a journey that begins when Dylan and Shep’s path intersects
with that of Jillian Jackson. Before that evening Jilly was a beautiful comedian
whose biggest worry was whether she would ever find a decent man. Now she too is
a carrier. And even as Dylan tries to convince her that they’ll be safer sticking
together, cold-eyed men in a threatening pack of black Suburbans approach, only seconds
before Jilly’s classic Coupe DeVille explodes into thin air.

Now the three are
on the run together, but with no idea whom they’re running from–or why. Meanwhile
Shep has begun exhibiting increasingly disturbing behavior. And whatever it is that’s
coursing through their bodies seems to have plunged them into one waking nightmare
after another. Seized by sinister premonitions, they find themselves inexplicably
drawn to crime scenes–just minutes before the crimes take place.

What this unfathomable
power is, how they can use it to stop the evil erupting all around them, and why
they have been chosen are only parts of a puzzle that reaches back into the tragic
past and the dark secrets they all share: secrets of madness, pain, and untimely
death. Perhaps the answer lies in the eerie, enigmatic messages that Shep, with precious
time running out, begins to repeat, about an entity who does his work by the light
of the moon.

By the Light of the Moon is a novel of heart-stopping suspense and
transcendent beauty, of how evil can destroy us and love can redeem us–a masterwork
of the imagination in which the surprises come page after page and the spell of sublime
storytelling triumphs throughout.
