Booklist Reviews

A year after the events of Greenglass House (2014), Milo and Meddy have yet another puzzle to solve. This time, a notorious map has gone missing just as a merry band of oddly costumed carolers arrive at the inn, and an infamous thief just might be the culprit. Milo and Meddy use their ample deductive skills, as well as garden-variety sneakiness, to uncover the scheme through a flurry of chaotic red herrings. Milford's sequel follows a very similar structure as the first book, but she keeps it fresh by significantly expanding on the mythology and history of Nagspeake, much of which ties into Milford's The Left-Handed Fate (2016). Her richly visual language brings scenes vividly to life, and while there's certainly enchanting magic to be had, Milo's talents don't come from supernatural gifts but rather his own imagination and intelligence, which is an empowering change from classic fantasy narratives. Occasionally, purposeful conversations drag down the pace, but those who love Milford's wildly imaginative world of Nagspeake will be delighted by this otherwise entertaining, magic-tinged mystery.

It's Christmas at Greenglass House again, and Milo is looking forward to a traditional Nagspeake holiday at the cliffside smugglers' inn run by his adoptive parents. But then Clem and Georgie, the young women thieves who helped make last Christmas so hair-raising (Greenglass House, rev. 9/14), arrive flush with loot from a heist gone wrong and pursued by a double-crossing associate. Unfortunately, the object they'd most wished to secure in the heist, a movable navigational map created by the formidable late smuggler Violet Cross, is missing. Milo is relieved when Meddy, the ghostly girl who helped him solve last Christmas's mystery, reappears and guides him in forming yet another alter ego from the role-playing game Odd Trails. Like Negret, the character Milo created the year before, Tengfei helps Milo handle his social anxiety, honor his Chinese ancestry, and penetrate the motives of the inn's idiosyncratic guests. Working on many levels, Milford delivers a head-scratching mystery, an eerie ghost story, hints of romance, and tales within tales that explore the (fictional) history of Nagspeake. Zollars's chapter-heading vignette illustrations honor the many overlapping layers that make up the story, from kid-friendly make-believe to curious artifacts of a forgotten age. And when it all comes together at the satisfying climax, readers might go straight back to the beginning to read the book again. anita l. burkam Copyright 2017 Horn Book Magazine Reviews.

Winter in the inn above the River Skidwrack finds Milo and his parents hosting several guests who are not what they seem—and a mystery to be solved. Just before Christmas Greenglass House is filled with unexpected visitors. A young man who claims to be an art student, studying the famous stained-glass windows of the house, is the sole guest until Georgie and Clem, young women who met the year before at Greenglass House, arrive. They've recently pulled off a caper, recovering a stash belonging to legendary smuggler Violet Cross. They hoped to find Cross' derrotero, an incalculably valuable nautical map of the impossible, changing River Skidwrack. And then a troupe of midwinter revelers arrives in a kind of Morris-dancing tradition, singing carols and traveling with the horned skull of a hobby horse and a chimney sweep. Milo and his parents invite the carolers in, but a ceremonial chimney cleaning results in an overnight stay—and the game is afoot. Milford's clever, complex plot is full of humor, tantalizing clues, and stories within the story. Adopted Milo, who has become conscious of the ways the world assumes things about him and his Chinese heritage, takes on a new hero persona that offers him confidence and insight into his emotions and strengths. A brainy, satisfying assemblage of puzzles with an immensely likable protagonist. (Mystery/fantasy. 10-14) Copyright Kirkus 2017 Kirkus/BPI Communications. All rights reserved.

Gr 4–6—The Greenglass House and Milo are back with a sequel to rival the first book. One year has passed and once again Christmas break is upon the Pine family—but, as luck would have it, this will not be the quiet holiday that the family craves. Between a suspicious art student, old acquaintances from last year's Christmas adventure, and a group of odd carolers, this historic house becomes the setting of yet another caper. Milo adopts a new persona and skill set from the role playing game Odd Trails to figure out who has stolen the mysterious derrotero of famed smuggler Violet Cross. This nautical map charts the impossible coast of Nagspeake; a map that smugglers and customs agents alike would desperately love to have in their arsenal. Milford artfully weaves a mystery that revolves around a large group of characters, new and old. Characters are quirky, scheming, funny, and not entirely what readers may expect. VERDICT A solid middle grade book best for those who appreciate a good plot twist and a great story. A recommended purchase for most libraries, especially where there are fans of the first installment.—Lisa Nabel, Tacoma Public Library, WA
