It's summer 1995 and Dan Willis is living in Santander, northern Spain, trying to get his life back on track, when he gets an unexpected call from an old school friend and Gulf War veteran, Billy Wyatt, who wants to visit him. Unbeknown to Billy, Dan invites two other school friends to join them. It’s a decision that will change their lives forever.
The Last Fiesta follows the friends’ hedonistic journey through the stunning Basque country, up into the Picos de Europa and finally to Pamplona, for the running of the bulls. But under the blistering Spanish sun, dark truths from the past emerge, and dreadful revelations entwine their lives in a way that will ultimately lead to disaster.
