I'll be participating this year too. My first Bonnie Hunter Mystery Quilt was last years and I love it. But, oh my, those chevron units -I still remember those,

. Looking forward to the color choices. I am betting there is red. I started watching what she had been working on this summer on her own 'retreats' and caught a few red four square patches before she went colorless photos!!!
Anyway, it is a guess and shows my enthusiasm for the upcoming project.
