Book 6 of the MONSTERSUAURS series.
Invisisuar the Ichthyosaur has always liked sitting quietly at the edge of things.
He listens more than he speaks, notices more than he acts, and is happiest when the world feels calm and balanced. But when Invisisaur begins to slowly fade from sight, he must face a change he cannot stop or fix.
As others learn to move forward without him, Invisisaur discovers that letting go does not mean being forgotten, and that belonging does not always require being seen.
