Olivia Millerschin will perform a holiday-themed show in Howell tonight and sign copies of her new children’s book, “Cactus on a Ledge,” in Saline Saturday afternoon at McPherson Local.

The Auburn Hills indie folk singer-songwriter will share her renditions of holiday and jazz standards while playing selections from her own catalog at 7 p.m. tonight inside the Howell Opera House, 123 W. Grand River in Howell.

Built in 1881, the Howell Opera House is a historic landmark in the city’s downtown, and the iconic venue’s first floor was renovated in 2006 for live shows and events.

For her Howell show, Millerschin will be joined by musicians James Pyne (trombone), Brian Riley (guitar) and Bob Mervak (keys).

“I have a couple of original songs and others that have been done by some of my favorite artists that are lesser known,” said Millerschin, who’s performed at the Howell Opera House twice before. “We’ll have some holiday classics by The Carpenters, and then we’ll play some of my own stuff.”

Millerschin also will celebrate the release of her new children’s book, “Cactus on a Ledge,” with a free signing, meet and greet, and performance at McPherson Local, 105 N. Ann Arbor St. in Saline, from 1 p.m. to 4 p.m. Saturday. Guests will be able to purchase the book at the gift shop.

“This is the first official store that’s going to be carrying the book, and it’s owned by these incredible people,” Millerschin said. “It’s all Michigan made products, so we just thought, ‘What better place is there to do this?’”

Millerschin didn’t initially plan to write a children’s book. Instead, she wrote an introspective ballad of the same name about a cactus who wants to become a tree, but soon realizes it’s cooler to be herself. After writing the song, family, friends and fans encouraged Millerschin to turn it into a children’s book.

She teamed up with a Matter of Fiction Publishing and artist Kathrin Honesta to compile and illustrate the book, which also includes a companion CD of the “Cactus on a Ledge” song. Honesta also did the cover art for Millerschin’s critically-acclaimed 2016 album, “Look Both Ways.”

To promote the book and song, Millerschin plans to visit local independent book stores, libraries and elementary schools in the coming months. The book will be sold in local shops, at shows and through Millerschin’s website.

“I just wanted to have something really organic and show the people who have supported me from the beginning first,” she said. “I sold almost an entire box of books at The Scarab Club in Detroit last Saturday during Noel Night.”

In addition to her upcoming book tour, Millerschin plans to record and release a live album soon.

“I’ve had a lot of frustration with making new music, and I’ve always had trouble with getting the right production down,” she said. “I’m at a point where we should just sing live with the full band, get right in the studio and release it that way. We’re going to be releasing a lot of new stuff, but just the live versions of it.”
