Fugitives!: A Story of the Flight of the Earls — Aubrey M. Flegg

A story of tension, danger and conquest.
When young Con disappears, the others must find him â€" and quickly. His father Hugh O'Neill, the great Ulster chieftain, is about to depart, forever. The Irish have lost at the Battle of Kinsale, and now there is nothing left for them in their own land. Hugh's son is in great danger â€" and he doesn't even know it! What would the English do to him if they caught him? Especially now as his father may be gathering another foreign army to threaten their own conquest of Ireland?

Can his cousin and friends, Fion, Sinead and James, find him? Will their hunt across wild landscapes, through dense woodlands and over high mountains, chased by English soldiers and adventurers, and occasionally guided by the mysterious 'Haystacks', take them to the boy? Will they manage to get him to Lough Swilly in time for the escape boat to France? The Great Hugh O'Neill is waiting anxiously …
