Wishin' and Hopin' by Wally Lamb

From Goodreads: It's 1964 and ten-year-old Felix is sure of a few things: the birds and the bees are puzzling, television is magical, and this is one Christmas he'll never forget.
LBJ and Lady Bird are in the White House, Meet the Beatles is on everyone's turntable, and Felix Funicello (distant cousin of the iconic Annette!) is doing his best to navigate fifth grade—easier said than done when scary movies still give you nightmares and you bear a striking resemblance to a certain adorable cartoon boy.
Back in his beloved fictional town of Three Rivers, Connecticut, with a new cast of endearing characters, Wally Lamb takes his readers straight into the halls of St. Aloysius Gonzaga Parochial School—where Mother Filomina's word is law and goody-two-shoes Rosalie Twerski is sure to be minding everyone's business. But grammar and arithmetic move to the back burner this holiday season with the sudden arrivals of substitute teacher Madame Frechette, straight from QuÉbec, and feisty Russian student Zhenya Kabakova. While Felix learns the meaning of French kissing, cultural misunderstanding, and tableaux vivants, Wishin' and Hopin' barrels toward one outrageous Christmas.
From the Funicello family's bus-station lunch counter to the elementary school playground (with an uproarious stop at the Pillsbury Bake-Off), Wishin' and Hopin' is a vivid slice of 1960s life, a wise and witty holiday tale that celebrates where we've been—and how far we've come.

This one was really fun! I can't remember how the author described the main character, Felix's appearance but I pictured him as the kid from A Christmas Story. The book just had that same vibe of 1960's America and, of course, it's Christmas. You read the description above and you get a feel already for how it is - just a romp with a few touching moments scattered throughout. I'll reread this one come Christmas time next year!
