I'd suggest going on the library online catalog or one of the bookfinding websites and searching for NC (nonconforming) or AD (adult-directed) lexiles in her range. NC and AD books are usually at a much lower interest level than their reading level, because they are intended for read-alouds or high-ability readers. A lot of picture books are quite high in lexile, but content-appropriate for a primary-age audience.

For example, try going on https://www.scholastic.com/teachers/bookwizard/
and searching for the desired lexile range and grade 1-2.
