                                    </ListBox>

IDictionary.GetEnumerator returns a collection of KeyValuePair<TKey, TValue>. So, in order to bind to your objects you need to use the properties on KeyValuePair.
Here is an example of how you can display the data.

<DataTemplate>
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
    </Grid>
    <!-- Display the day of week in the first column -->
    <TextBlock Text="{Binding Current.Key}"/>

    <!-- Display the books in the second column -->
    <GridView Grid.Column="1" ItemsSource="{Binding Current.Value}" />
</DataTemplate>
