LYNN – When Sarah Phelan’s seventh grade students found out she recently finished writing her second novel, they asked if they could read it.”No,” said the Breed Middle School teacher with a laugh. “No, you may not.”The book is not risque, but it is for adults, not young adults.Imagine you have the perfect life and just before you’re scheduled to get together with all your old friends for a huge wedding it all falls apart. That is the story Phelan tells in her second novel, “Plus One,” which will be officially released Friday.”But you can do pre-orders on Amazon.com now,” she said.Phelan published her first novel, “Stay at Home,” in 2006. She said she wished she were a more prolific writer who could produce copy more along the lines of Stephen King but that’s not her style.”Projects take me forever,” she admits. “And I do it for fun. I do it because I want to tell a particular story.”Actually, the writing part of the process doesn’t take all that long; it is the editing and the rewriting that become work, Phelan said.Working full time, caring for her mother and raising two children also adds up to not enough hours in a day for Phelan. She said her writing life was certainly easier when she wrote her first novel and her kids, now 11 and 13, were small.”We put the kids to bed at 8 p.m. and then I could work,” she said. “Now it’s squeeze in an hour here and there. I have to be a lot more disciplined.”Julia Rosa, the main character in “Plus One,” is disciplined. Wife, mom and wedding planner for a large New England hotel chain, Rosa is focused, until her husband leaves her and she is obligated to face her friends for a wedding weekend without her “plus one.”Phelan said after writing about a stay at home mom in her first novel she wanted to tackle a working mother but she wanted that detail to be more of a character trait than the main focus.”I wanted to show that working mothers have to make decisions ? but I didn’t want her to apologize for those decisions or any decision,” Phelan said. “At the same time all decisions have repercussions.”When asked where she gets her story ideas Phelan laughed.”I have weird dreams,” she said. “If something really interesting strikes me I try and write it down. It could lead to 40 pages of nothing but every once in a while…”With nearly seven years between books Phelan said there were times she agonized over whether she had a second novel in her.”My husband kept saying it would come and it did,” she said.Readers should also note that while the characters in the story might be inspired by actual people in her life they are in fact fictional, which is to say that her husband is not leaving her, she said. She said someone did ask her husband if everything was okay.She said if anyone in her story does resemble someone she knows chances are they resemble others as well.While her students won’t get a chance to see if they turn up in any of Phelan’s stories any time soon Phelan said she has not ruled out the idea of writing a young adult novel.”I think it would be fun,” she said. “Especially since in the last few years there has been so much great literature out there for them.”In the meantime Phelan will gather with family and friends for a small book launch party at Red Rock Bistro Friday, where she plans to “revel in the glory” of a finished novel, before she begins to agonize if there will be a third.
