Sound Familiar?

Your child struggles with big feelings — worry before school, meltdowns over small things, and difficulty winding down at night.You've tried apps, but more screen time isn't the answer.
You've tried books, but they sit unread on the shelf.
You've tried talking, but the conversations feel forced.

What if there was something different?

"3 in 4 parents worry about their child's emotional wellbeing."

- NSPCC, 2024

Meet Ari

Ari is 9 years old, loves drawing, and sometimes worries about things other kids don't seem to notice.When a magical postbox appears in Gran's garden, Ari steps into a world of gentle creatures — and discovers that big feelings aren't something to fix. They're something to understand.Through 24 letters, your child journeys alongside Ari, learning real calming skills woven into every adventure. Each letter feels like a note from a friend — because that's exactly what it is.

What arrives in each envelope

Frequently Asked Questions

Ages 7-12, with layered complexity that engages both ends of this range.

Younger children (7-9) connect with Ari's adventures and concrete skill practice. Older children (10-12) notice deeper themes about identity, emotional complexity, and self-understanding.

The fantasy format works across this full age range - the same approach used by Harry Potter and Percy Jackson. What prevents the "babyish" feel: realistic struggle, genuine consequences, and skills that help "a little" rather than magically fixing everything.

You'll receive 2 letters per month for 12 months — 24 letters in total. Each letter builds on the last, so your child develops skills progressively through Ari's complete journey.

Choose monthly (£17/month) or annual (£170/year — save £34).

Read the first two letters with your child. If they're not excited to receive the third, we'll refund you completely — no questions asked.

Annual subscribers: Full refund within the first 30 days.

Monthly subscribers: First month refundable. After that, cancel anytime — no refunds for the current month, but no further charges.
