This is a review of the 3 books so far, together, because they showcase the complete trip from leaving Virgil, their friends, and their Granny, to arriving and making their claims for land on their arrival.
The preparations occur on the setting of Eva's pa insisting Eva marry Harold, the son of a well-off shopkeeper, who is a bully and selfish. Pa Thompson has known poverty and he doesn't want his children ever to know want such as he has known. But Eva loves honest, hard-working David, son of the town drunk, his father's drinking something most of the people in Virgil believe is his fault somehow. He hires on with a family since he can't afford the trip on the money he has saved so far. Once on the trail, his work ethic gives him credibility in the sight of people who take him at face value. Eventually, the blinders come off about Pa Thompson's preferred son-in-law and he realizes his mistake - with a bit of help from his wife. Eva and David finally get married with the family's blessing.
Twins Becky and Johanna are about as opposite as 2 people can be. Becky is vivacious, outgoing, tomboyish, a flirt, and has fallen hard for Capt. Scott Jones, the trailmaster, who is 10 years older than she, and their relationship is stormy throughout their time together. A quiet love develops slowly between Rick and Johanna, her good feelings about their relationship souring briefly when the 23 year old bachelor Rick sees no way to care for his 2 nieces and pursue his dreams at the same time, and is panicky about doing right by the 2 girls, who have lost a mother and 2 brothers to sickness on the trail. When the girls, esp. the 10 yr old, get sick, and the 10 yr old seems to be giving up fighting for life, he realizes just how much he loves them, and as he bathes the little girl in the cold water of the creek, trying to get her fever down, he tells her. She recovers, and Johanna realizes she loves him and that things stand a chance to work out. The 2 of them gain an additional family member when one of Johanna's little protectors, Almanzo, who has been taught hate by his father, is found beaten and running a high fever. Johanna, who has just gotten done running a miniature hospital of very sick people, isolating the sick and limiting caregiviers to slow the spread, finds herself once again nursing someone back to health. She reads to him from Rick's older niece's book of fairy tales, making the main characters princes instead of princesses at the girl's suggestion. When she finds out what happened to the child, she tells him he will always have a home with her, and her parents reassure him - as does Rick. A terrible accident takes a young man's life, and his fiancee is devastated. She loses the will to live when she gets sick. Johanna does all she can to help the girl see her fiancee would have wanted her to move on, but though it takes a while, she does finally return to herself and fight for her life against the illness. Two died in the small epidemic that hit the wagon train group, but the rest are ok. Johanna's work with sick people ends up giving her some fame among the Indians, where she goes, with Becky and Scott, to help a sick Native American woman, Scott's sister in the tribe. There, Becky discovers more about Scott, including that his wife and kids were killed by the nasty man they recently met at a fort on their journey. Scott had taken him in for trial as a land pirate who killed both Indians as well as a white wagon train full of settlers, and done so dressed as if he were an Indian. They had assured Scott he'd hang for his crimes, yet there he was, free again. Scott wants revenge and knows he himself might hang for murder, thus he has done what he can to distance himself from Becky. It is a topic of discussion with Scott's tribe. While the girls are there, trying to make sure the sick woman recovers, Almonzo shows up as Johanna's protector. Paco, Scott's brother, has his son Tall Trees, look to educating Almonzo somewhat in Indian ways, and more so than the adults realize. When Paco, Beaver aka Akmid, and Becky are kidnapped by the land pirate and his accomplices - one of whom worked with Harold the storekeeper, the other being Almonzo's father. Paco is badly beaten for trying to defend Becky. Scott and David, who has become the wagonmaster's 2nd in command, set up a way to rescue the kidnapped and get the bad guys. The tribe to which Scott belongs is split on the issue of war with the whites, but most Whites don't know that. Akmid gets free and frees Paco, but is unable to free Becky. He takes Paco to the wagon train so Johanna can care for him. Paco warns them of the 2 factions in the tribe. We see the bravery of Almonzo once again, as he rides, bareback as Tall Tress taught him, and with Paco's necklace on as proof to both horse and tribe that Paco sent him. He brings back help.
The bad guys are finally defeated, one with the sabotaged gun that was Johanna's suggestion. All 3 land pirates are dead, and in a pitched battle, so no one can lay a homicide charge at anyone. Will Scott keep pushing Becky away, or will he finally settle down and ask for her hand in marriage? And what about Rick? Johanna has already accepted his proposal of marriage, and he can no longer think of surviving without his nieces and Almonzo. Can he really stand to be away from them for months at a time, trying to set up schools all over the West, or will he stay put and start one school where he is and enjoy his mix and match family and his new wife, and perhaps add more children to the mix one day? Perhaps pass his dream on to others?
Love is in the air for all ages as well. But no one wants to settle near the first town to which they came - all that seemed to be there were saloons, brothels, and gambling houses, with even the general store being an afterthought. They decide to move nearer to Portland which is more family friendly. They stake their claims and get ready to build houses for everyone.
But to find out what decisions Rick and Scott make about the twins they love, and who else fell in love on the trail, you'll have to read all the books.
The next one in the series.is about Almonzo, 10 or so years later. Towards the end of the trip, Almonzo was crushing hard on Rick's older niece. Even if they're raised together, they're not related. Many crushes, esp. at age 10, don't last, but we will have to read the next book to find out if this one did.
