The Penderwicks: A Summer Tale of Four Sisters, Two Rabbits, and a Very Interesting Boy: Latin-enthusiast Martin Penderwick certainly has his hands full with four daughters. Motherly Rosalind, tough, no-nonsense Skye, ditsy Jane and be-winged Batty embark on summer vacation at the cottage of Arundel, which lies on the grounds of the great Arundel Hall. There they meet and eventually befriend Jeffery, a musician and son of Arundel's owner, the dreadful Ms. Tifton. While Jane struggles with her novel-writing and Batty falls in love with the gardener's rabbits, the girls must find some way to keep Jeffery from being shipped off to a military academy by his mother and even-more-dreadful, soon-to-be stepfather, Dexter Dupree.

​

The Penderwicks on Gardam Street: Aunt Claire delivers a letter from the deceased Mrs. Penderwick, expressing her desire for Mr. Penderwick not to remain lonely. Much to the girls' dismay, Claire then organizes a series of dates for Mr. Penderwick to go on. The Save-Daddy Plan is hatched: find the worst possible women for their father to date, so that Claire will finally let up and life can go back to normal. Enter Iantha Aaronson, the astrophysicist neighbor, and her young son Ben; the endearing but irritating Geiger brothers, Nick and Tommy, who force the girls to do football drills with Mr. Penderwick's blessing; Bug Man, a figure whom Batty is convinced is stalking Gardam Street; and many more.

The Penderwicks at Point Mouette: It's summer vacation again, and what better way to spend it than with Aunt Claire and Jeffery? While Mr. Penderwick embarks on his honeymoon and Rosalind goes on a trip with her friend Anna, the youngest three girls travel to Point Mouette, Maine and meet Jeffery at their cottage. Batty discovers a love for moose, music and collecting golf balls, while Jane falls in love with Dominic Orne, a cool and utterly idiotic skateboard-rider. Aunt Claire sprains her ankle, so Skye, as OAP (Oldest Available Penderwick) has to kick it up a notch with her responsibilities. It doesn't help that she's somehow convinced herself Batty's going to blow up. Fortunately, she has help from Jeffery and their neighbor, Alec, who is also a music-lover and might just be the key to Jeffery's past.

​

The Penderwicks in Spring: Years later, while Rosalind is off at college and Skye and Jane are suffering through highschool, Batty and Ben embark on their own adventures. As Batty starts a dog-walking business to earn money for voice lessons, she and Ben must survive a visit from Rosalind's horrible film-major boyfriend Oliver, find comfort in the return of Nick Geiger in all his football-enthusiast glory and keep Skye from murdering Jeffery. While the world goes crazy around her, Batty has to sort out her own feelings about her mother, the passing of a much-loved family pet, and sibling rivalry.

​

The Penderwicks at Last: Lydia Penderwick is eleven, and she's dancing while waiting for her older sisters to get home from college. This summer, Tommy Geiger and Rosalind are getting married--and Jeffery is coming all the way from Germany for the wedding! The wedding plans suddenly change when Jeffery offers to host the wedding at Arundel, which he now owns. With the promise that his mother is in New York, the Penderwicks happily accept the invitation. Lydia and Batty arrive at the mansion weeks in advance to get everything ready. On arrival, Lydia is not only amazed by the wonderland from her sisters' stories, but she also meets Cagney's daughter Alice. Everything, Lydia is sure, will go smoothly if Ben only refrains from bossing her new friend around. But when Ms. Tifton suddenly appears at Arundel, the sisters know they're in for more than they bargained for.
