After the death of his beloved wife, Nikki, Cal is struggling to move forward. Hoping to honour her memory and reconnect with his teenage stepdaughter, Zoe, he plans a meaningful interrailing journey across Europe to Zurich, where Nikki is due to receive a posthumous award.

But the trip doesn't go quite as planned. Unknown to Cal, Zoe has invited other family members to join them, turning what was meant to be a quiet journey into an unexpected family reunion. As they travel across Europe, long-held secrets emerge, old tensions resurface, and each member of the family is forced to confront their grief in their own way.

Warm, funny, and deeply moving, On We Go is a beautifully observed novel about healing, forgiveness, and discovering that even after heartbreak, family can help us find a way forward.
