My mother-in-law recommended this book a couple of years back. The only thing I really know about it is that it's set in Detroit -- Grand River and Joy are streets downtown. (You can see the intersection here on Google Maps, if you're interested.)
Random note about the street "Grand River." On the freeway, it's abbreviated "Gd River" and the GPS also says "Gd River." When we first moved here, I was using the GPS to navigate and I told Bill, "Get off at Grand (?) River. At least, I assume that's 'Grand' -- it's abbreviated as 'Gd' everywhere -- it's not God damned River, is it?" You never know -- Detroit can be pretty tough! Heh.
I'm also currently reading Detroit City is the Place to Be and Belle Isle to 8 Mile: An Insider's Guide to Detroit, which is an exhaustively comprehensive guide to the city. (Honestly, I have never read a more detailed city guide in my life.) So, you know... I'm gettin' all Detroit-y!
