Twinnin' Ain't Easy - L. A. Boruff - Bog

Things are topsy-turvy in Wears Valley, and Lela and Mae must get to the bottom of it all before someone ends up dead... or worse.
After barely saving their Aunt Bertha's life, Lela and Mae know their time is limited to find the attacker. But magical happenings start making local headlines. They can't help but get involved, and in the process, they discover a whole community of witchy friends who are just as stumped as the twins are about magic suddenly appearing in the mountains again.
And now there are any number of suspects. Could it be the handsome nurse, George? Lela says no, but Mae isn't convinced.
Lela suspects Mae's new professor friend. He seems all stuffy and reserved at first, but Mae soon discovers just how hot things can be under the surface.
Bertha is just glad to be alive, and together with her and Harriet, the twins discover more about their heritage, their bond as twins, and their future.
