I'm trying to write about footy and my grandson and me. About boys at dusk. A little life-hymn. A poem. A record of a season we spend together before he turns into a man and I die.

It's footy season in Melbourne, and Helen Garner is following her grandson's under-16s team. She not only goes to every game (give or take), but to every training session too, shivering on the sidelines at dusk, fascinated by the spectacle.

She's a passionate Western Bulldogs fan with an imperfect grasp of the rules, who loves the epic theatre of AFL football. But her devotion to the under-16s offers her something else. This is her chance to connect with her youngest grandchild, to be close to him before he rushes headlong into manhood. To witness his triumphs and defeats, to fear for his safety in battle, to gasp and to cheer for his team as it fights for a place in the finals.

With her sharp eye, generous wit and warm humour, Garner documents this pivotal moment, both as part of the story and as silent witness. The Season is an unexpected and exuberant book: a celebration of the nobility, grace and grit of team spirit, a reflection on the nature of masculinity, and a tribute to the game's power to thrill us.
