Book Zero in the Hadron Damnation Series.

Socially awkward DCI Tracy Hanson is having a bad day. 

It starts with a commercial flight crashing into the heart of London. She is chased by out-of-control helicopters. There’s a mysterious sniper on the loose. Her boss is giving her grief. Her work colleagues are giving attitude. And now she has a new and distracting partner, jealous girlfriends, a boy orphaned from the crash site, and a two o’clock appointment at the IVF clinic. 

Hanson hunts down the rogue sniper, but each clue forces her to face the truth behind her broken past, each revelation leads her toward the impossible. A net draws in around her as events spiral out of her control and the city turns on itself. 

In the houses of power, politicians and the military twist the crumbling civilization to bolster their own agendas oblivious to the destruction they are ushering in. 

And that's before the aliens attack.

See how it starts.

For four hundred years, the human race has been hiding, defending, surviving against an unknown alien attack, using weapons known as rippers and smashers.

Except they are not weapons, they are children—descendants of Cally—with unique abilities to rip open the space-time continuum and smash through to one moment in the future, and broadcast back what they glimpse before they die. But one day, a child comes back …

... with the truth.
