All the things that you've lost - that you've loved - are not gone, When they're held in your heart, a small part still lives on... Together Grandad and Ava adventure along the twisting path and over the hill where, beneath the canopy of their friend the old Oak tree, they make wonderful memories to treasure and share: from summer picnics with jam-sticky fingers to carefree days kicking through russet leaves in autumn's soft glow. But as the seasons change, so too does the old Oak tree and Grandad's health .
