Max Hamby and the Faeryn Cross by Kathy Cyr

Bonedread has escaped and he's on a mission to get paid one way or another.
The first order of business is to auction off Celadine and get as much money as he can for the elder dwarf's daughter.

Max, Milo and the twins cannot leave Merrihaven and are being closely guarded by an army of pixies. Time is running out. Three stones have been found, but four more are out there and no way to get to them.

With a little help from Roanin, the search for Celadine and the other stones is on.
But, the trouble is far from over when they come in contact with a strange creature that can rot their magic and kill them with one touch.

Celadine's every attempt to escape
has been thwarted. Her last chance for freedom ends when she's sold to the Black Order. Rumor has it, she's to be their sacrifice to a demon.

Max's parents and Milo's mom and grandma are fading away in the Shadowlands.
Isolde is getting stronger by the day and Max is finding it harder and harder to astral jump back into his body.

There's been no sign of Birdie, Tommy or Alice. Two Trith are on the loose and Ole Black awaits them in a dark cave.

Will the other stones ever be found.
