Ellie designs and builds a basic elevator (picture a movable platform) for hoisting things up to her playhouse/workshop. Unfortunately, the dry run ends in a wet mess when 24 pickle jars crash to the ground. As punishment, she agrees to help Mrs. Curran, an elderly neighbor who paints dolls for a living. Friends Kit and Toby volunteer to join her. At first their jobs are boring (stuffing envelopes, dusting), but when Ellie talks Mrs. Curran into helping them build an elevator for hauling art supplies up to her painting studio, their project succeeds. In an appended section, Ellie introduces readers to simple machines, like the elevators' pulleys. Woven through the story is Ellie's distress when Mrs. Curran can't seem to recognize that Ellie is the engineer in the group, not Toby, or that he enjoys playing with dolls, but they find ways to let her know. Childlike line drawings of gadgets and the generous use of white space add to the visual appeal of this enjoyable chapter book, a sequel to Ellie, Engineer (2017).

Dress-loving engineer Ellie navigates prescriptive gender roles and interpersonal misunderstandings in this middle-grade STEAM-championing series. Ellie prepares a doghouse for best friend Kit's birthday in the opener; in Next, Ellie and friends help an elderly neighbor woman, who gives boy Toby all the credit for Ellie's projects. Sufficient action and tension, enjoyable inventions, and appealing characters balance the stories' messaging. Illustrations include engineering sketches.

Kirkus Reviews

Ellie and her friends from Ellie, Engineer (2018) return for more mishaps while proving anyone can be an engineer.Ellie, Kit, and Toby use a pulley to build an elevator for Ellie's workshop, both so they won't have to carry supplies up the ladder and so the workshop will be accessible to people like Ellie's grandmother and a school friend who uses a wheelchair (the latter is mentioned but doesn't appear in the story). Unfortunately, the design fails, dumping and shattering its massive (and borrowed-without-permission) pickle-jar payload. Ellie's punishment consists of helping elderly neighbor Mrs. Curran for a week. With Kit's help, Ellie plans all sorts of inventions she could make to help a grandmother type only to find that stereotype-breaking Mrs. Curran's an appearance-focused doll artist who does not bake cookies and who has sophisticated tastes. When Toby joins the girls at Mrs. Curran's house, the team starts to use their engineering know-how to make repairs and improvements—but though she's appreciative, Mrs. Curran can't wrap her head around the fact that Ellie is the brains of the operation, and she defaults to crediting Toby. To help Mrs. Curran realize that girls can be engineers, they scheme to show her she can be one herself, with an improved elevator design to help her carry her art supplies up to her studio. One last twist complicates their plan before the happy ending. The thematic parallel that compares limited expectations of both girls and the elderly works well, but it isn't subtle. The cast seems to default to white.A structurally sound story about challenging assumptions and responsible engineering. (guide to simple machines) (Fiction. 7-11)

School Library Journal (Mon Oct 01 00:00:00 CDT 2018)

Gr 2-4 The second book in the series focuses on Ellie's struggle to be accepted. When Ellie and her friends help their elderly neighbor, Mrs. Curran, by fixing up her house, the older woman believes that Toby, not Ellie, is responsible for the engineering and building. Ellie and her friends work to convince Mrs. Curran that girls can be engineers, too. The plot delves more deeply into gender stereotyping than the first installment, and the protagonist's frustrations are something with which many young girls will identify. Ellie is an intrepid problem-solver who knows who she is and what she loves to do. She is able to stand up for herself and, eventually, convince Mrs. Curran that girls and women can do and be anything. Illustrations of Ellie's creative ideas and designs are included as is as a guide to simple machines. VERDICT A solid STEM-themed book with a strong focus on empowering young women to embrace and pursue their interests. V.
