Becoming Forest opens
with Aishling--the young Irish woman at the heart of this story--as she visits
her grandmother in California following her grandfather's death. Aishling finds
her grandfather's journal and reads about a trip he made to India years ago to
visit the original Bodhi Tree, the place where the Buddha found enlightenment.

At the end of the journal, she finds a letter addressed to
her from her grandfather asking for her help passing along his message of "deep
security" to her generation as they deal with the climate crisis and the
uncertain future ahead. Aishling goes to India to follow in her grandfather's
path to find a way of responding to his request. There she meets and falls in
love with a young Buddhist monk, who is also on a quest. As they walk together along
the roads of India, they gather unexpected and invaluable insights from each
other and come closer to the answers they both seek.

Thirty years later, Aishling's daughter Tara is
visiting her in Ireland. Tara is grieving the death of her father and also the
destruction of the forests from drought and fire. She is also searching for a way
to heal the burnout she and her friends are experiencing while working to
combat climate change. Becoming Forest
weaves together threads of Native American and Celtic spirituality with
Buddhist understanding and connection to the natural world, creating a tapestry
which holds both the despair and awakening of Aishling
