The Dwarons and the Valley of Hope - Grant Paul B. F.

Dwarons are a weaker, smaller variety of dragons who were treated as misfits; rejected and excluded by the fierce and more powerful dragons - but who survived long after those dragons had become extinct.

In this second book of the Dwaron series, the Dwarons' idyllic existence on the secluded island of Divinia appears to be under serious threat, until they are able to find the 'light at the end of the tunnel'.
