The Dactyl Hill Squad, led by Magdalys Roca, is on the move, heading south to find her soldier brother, who is missing in action during the American Civil War in this alternate-­history adventure yarn. As their dinosaur friends fly them over Tennessee, they become embroiled in the fighting, and Magdalys' skill wrangling dinos is uncovered. She may not be the only talented one, though, and her abilities may not be enough to help the Union Army turn the war their way. History comes alive, with dinosaurs and spies added to actual battles like Chickamauga and Milliken's Bend. Older also continues to shine a light on heroic people of color, such as those in the Louisiana 9th Division, the Black army doctors whose wartime practice was limited to treating African Americans and camp animals, and Native American General Ely Samuel Parker all soldiers and officers who faced animosity from their white counterparts, even while fighting beside them. An author's note provides further information about the people, places, dinosaurs, and weaponry mentioned in the book.HIGH-DEMAND BACKSTORY: Older has middle-graders' number with this dino-charged series.

Gr 4-7-In this second installment of the series, Magdalys Roca and friends fly into the midst of the raging Civil War hoping to reach her wounded Union soldier brother in New Orleans. The book opens during their journey south from New York when, atop the giant Pteranodon Stella, squad member Cymbeline calls for an enigmatic stop in Tennessee. The group soon discover her true role in the war as they meet with Union General Sheridon's dino-mounted Louisiana Native troops, an African American regiment. High levels of tension and danger ensue as Magdalys witnesses the horrors of war while tamping down her increasing ability to communicate with and control various types of dinosaurs. She even saves the life of Gen. Ulysses S. Grant and is called upon to use these talents in the war effort. As her friends go their separate ways, she learns that her brother is in grave danger, and she faces a difficult decision: buck the odds of survival to locate her brother, Montez, or assist the army for the greater good? This series deals with the consequences of war, the racism of both Northern and Southern whites toward individuals of Native American, African American, and Afro-Caribbean heritage, and the pains of growing up during this era. An author's note provides backstory, although the addition of a map of the United States, Mexico, and the Caribbean would be helpful. VERDICT This series installment will draw readers in with its fast-paced action, likable characters, and fantastical twists on Civil War history.-Ruth Quiroa, National Louis University, Lisle, IL © Copyright 2019.

Magdalys and company return in this sequel to Dactyl Hill Squad (2018).On their way with their pteranodon to New Orleans to rescue Magdalys' injured Union soldier brother, the squad falls in with the all-black Louisiana Native Guard (that they're not Native American is commented on), led by Gen. Sheridan. Secrets soon start to spill: The sole adult in their crew, thespian Cymbeline, is actually a Union spy, and when Sheridan discovers Magdalys is a dino-wrangler, he tries to inveigle her into Union service. Magdalys feels betrayed by Cymbeline, wants to prioritize her brother, and understandably doesn't trust Sheridanbut that doesn't save the squad from getting pulled into battle. The rapid pace is akin to the first installment's but smoother, and as the squad navigates peril after peril, the supporting characters come into their own. As Afro-Cuban Magdalys recognizes how putting her power in Union hands could help enslaved black people, she vacillates. Showing great respect for his readers, Older doesn't pull any punches. Amaya, who is Apache, points out the irony of fighting for people who stole Native land. Later, Magdalys grapples with the unpleasant truth that (most?) Northerners would happily keep black people enslaved in exchange for an end to the wareven Gen. Grant himself. Readers will be relieved that in a cruelly unjust world she gets a happy ending, though it's clear her story is far from over.Blisteringly paced, thought-provoking adventure.
