Rory and the Balloon Bicycles

Rory the dragon and his best friend Flora share a love of flying and
bicycles, so they are shocked when they discover a mountain of
discarded bikes, and appalled when they realise that rust from that
mountain is running into the dragon clan's drinking and gardening
water.
More and more children start discarding their old, sturdy bikes in
favour of brightly-coloured, plastic, inflatable, single-use
replacements which look great (they even sort-of fly) but pop easily
and cause injuries on impact - facts which are of no concern to
Evilyn the Entrepreneur.
It's up to Rory and Flora to put an end to Evilyn's schemes and repair
and recycle all the damaged old bikes, before anyone gets seriously
hurt.
A magical adventure story for children aged 6+, with themes of
resilience, teamwork and sustainability.
