Orphan Johnny Dunne has fled Balbriggan, where he spied for the rebels in Ireland's War of Independence. Now he has a new and even more dangerous mission. Rebel leader Michael Collins engages in a cut-throat secret war with British Intelligence: and Johnny, Ireland's youngest spy at only fourteen years of age, finds himself at the centre of the action. In a Dublin full of gunmen, soldiers, police informers and the dreaded Black and Tans, Johnny has to watch his every move.

But it's hard to turn his back on the past, especially on his friendships with Alice Goodman, and with Stella Radcliffe, the daughter of a British officer, who risked her own life to save his.

As the War of Independence grows more lethal, the three friends must decide where their loyalties lie. Then a secret from Johnny's past changes everything...
