Book is The Female Brain by Brizendine.
Got a reply from Kobo support today:
Thank you for contacting Kobo Customer Care. We are more than happy to assist you today.
Look out for the capitol A and the small a when you have your eReader open and change the font. There is nothing else that can be done.
When I preview the Kindle edition on Amazon, it's clearly black print. I may see if a free book has the right font color. If not, it will be returned. I'm so frustrated as the rest of my book group is waiting to hear my experience. We all want to support our local book stores.
I appreciate all the replies, even the ones I don't understand
