Rebel Hearts: Journeys Within the IRA's Soul, by Kevin Toolis (Picador, £7.99 in UK)

Five years since it was first published, Toolis' emotional, new journalism mix of personal experience and first-class reporting about the Provisional republican movement is still a terrific read. The reissue contains additional chapters on the IRA's murder of its renegade Newry member, Eamon Collins, and on the group behind the Omagh bombing. But the new chapters lack the intensity of his earlier work. His travels and research over a decade from the mid-1980s brought him remarkably close to people in the republican heartlands and they, in turn, were remarkably open with him. The journey is also back to his own family's roots from their banishment to Achill in the Cromwellian clearances to his parents' emigration to Edinburgh in the 1950s.
