Even writers make mistakes.
If you have downloaded Rosalind, I need you to delete it from your manage Kindle section and buy it again (it is still free tomorrow). The wrong version of the book made its way onto Amazon. Terribly mistake. If you can tolerate the few remaining errors, then no need. But if it is distracting, the new version will be up by 8 AM MT tomorrow.
I thank you for your patience.
