Mr. Potter's given us a bold adventurous book with plenty of sharp turns at high speed, with some gestures toward Neruda and Merwin but also "Sk8," a gr8 skateboarding poem, and sonnets, and brave ventures into rhymed verse, poems for friends and relatives, "Stopping By Blogs on a Frosty Evening," and poems of passionate love with angels looking down from above. Plus tulips and Elsie. ---Garrison Keillor.
