Savage Children - Peter Boland

FROM #1 BEST-SELLING AUTHOR IN AMAZON CRIME ACTION & ADVENTURE.

Children are disappearing from London parks. Caught on CCTV, they go in but never come out again...

Days after each disappearance, the distraught parents receive a hand-drawn picture of their child as an angel. A sign they'll never see them again. The police have no clues or leads. All they have is a nickname for the abductor - the Archangel.
When Savage's neighbour's ten-year-old son Callum becomes a victim, he vows to find him, and catch this Archangel. Savage has his headstrong friend Tannaz to help him. This time it's going to take more than her brilliant computer skills to find the truth. They'll have to enlist the help of some new friends - and some old enemies.

As more children go missing, Savage realises the Archangel is a formidable adversary. Clever, elusive and terrifying. Savage also has the police on his back, watching his every move. The deeper Savage becomes involved, the more he realises all is not what it seems...

A twisty, chilling, action-packed thriller for fans of Lee Child and David Baldacci.
